Answer:

Synthetic, cotton

Explanation:

Synthetic fabric wrinkles less than cotton fabric.

Wrinkle is known to be an unusual fold, ridge or crease in the cloth. Some cloth experience this type of wrinkle why some do not. The material of the cloth determines its ability to wrinkle.  Synthetics are known to be more wrinkle resistant than cotton and even linens. 100% linen or a blend of cotton/linen. Even polyester clothes are more wrinkle resistant than cotton.

Ignorance of animals’ stress response

Explanation:

Dr. Temple Grandin who is a researcher on the various animal stress and how to ensure that animals are taken care of published an article on what animals passed through daily during animal operations.

According to him, the most common cause of abuse and neglect in animal operations happens to be ignorance of the people about animal stress response.

To him, most farmers don't pay attention to the stress animals passes through neither do they respond adequately to those stress when found.

Drug, medicine, or poison: Muscarine; Looks similar to this endogenous molecule: Acetylcholine; Binds to this endogenous protein/receptor: muscarinic receptors

Drug, medicine, or poison: Tamoxifen; Looks similar to this endogenous molecule: estrogen; Binds to this endogenous protein/receptor: estrogen receptor

Drug, medicine, or poison: Prozac; Looks similar to this endogenous molecule: Serotonin; Binds to this endogenous protein/receptor: serotonin transporter protein

Drug, medicine, or poison: Ketamine; Looks similar to this endogenous molecule: NMDA; Binds to this endogenous protein/receptor: NMDA receptor

Explanation:

Muscarine is a poisonous natural product found in certain mushrooms. It is similar to acetylcholine and competes with acetylcholine at its receptor binding sites.Signs of muscarine poisoning include salivation, lacrimation, vomiting, diarrhea, abdominal pain, bradycardia, etc.

Tamoxifen is a selective estrogen receptor modulator. It is similar to estrogen and acts by inhibiting the effects of estrogen in the breast tissue. It is used to prevent and treat breast cancer in men and women.

Prozac is an antidepressant which belongs to th class known as selective serotonin reuptake inhibitors. It looks similar to serotonin and inhibits its action by competing with serotonin for its binding site. It is used for the treatment of depression disorders.

Ketamine is an NMDA (N-Methyl-D-aspartate) receptor antagonist. NMDA receptor antagonists are a class of drugs that work by inhibiting the action of the NMDA receptor. They are commonly used as anesthetics for animals and humans to induce a state of anesthesia known as dissociative anesthesia.

Answer: Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body.

Explanation: Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Answer:

This is an example of positive feedback response

Explanation:

Positive Feedback Response in Biology is said to be a phenomenon that occurs when the product or the output of an event or that of a reaction changes the response of an organism to that reaction. Positive feedback response can also happen so as to increase the change or output, then the result of the reaction gets amplified and thus leading to it occuring more rapidly.

An example of positive feedback response is the one from which this question was asked. Another is uterine contractions that takes place childbirth. The hormone oxytocin, created by the endocrine system, goes on to stimulate the contraction of the uterus.

Explanation:

To know if two genes are linked or assort independently, a testcross can be performed. If the progeny distribution differes from the expected ratio, they are linked. Extected numbers: -100 curved wings, ebony body -100 curved wings, gray body -100 straight wings, gray body -100 straight wings, ebony body.

Independent assortment law establishes that the alleles from two or more different genes distribute independently from each other in gametes.

Each gamete receives an allele from a gene that does not depend on nor influence another gene's allele in the same gamete. This event only occurs in independent genes. These genes segregate independently after crossing over because they are far away from each other.

Some other genes, however, are too close to each other, and they do not segregate independently. These are the linked genes. They do not exhibit an independent distribution, and they are inherited together more frequently.  

To know if two genes are linked, we must observe the progeny distribution.

In the exposed example,

1st Cross: flies with curved wings and gray bodies to flies with straight wings and ebony bodies.

Parentals) ss GG   x   SS gg

F1) 100% Ss Gg

2nd cross: F1 individuals testcrossed

Parentals) Ss Gg   x   ss gg

F2)  

Total number of individuals: 400

Hypothesis: Both genes assort independently from each other.

We need to give the expected values. As said before, the expected ratio is 1:1:1:1 ⇒ 4/16 Ss Gg : 4/16 Ss gg : 4/16 ss Gg : 4/16 ss gg

16 possible genotypes --------------- 400 individuals

4 Ss Gg ----------------------------------- X = 100 individuals

4 Ss gg ----------------------------------- X = 100 individuals

4 ss Gg ----------------------------------- X = 100 individuals

4 ss gg ----------------------------------- X = 100 individuals

The expected numbers are

Gymnosperm

Nonflowering and exposed seed

Gymnosperms are the group of plants that do not possess or produce the egg in the enclosed seed which makes there seed naked or exposed

Pine or fir trees

Fir and pine are trees, and more specifically conifers, which belong to the family Pinaceae. of the gymnosperm

Angiosperms

Garden flowers and tomatoes

Tomato plants and garden flowers are the plants that belong to flowering plants or angiosperms.

Seeds enclosed in fruit

In angiosperms, there is a closed ovary that enclosed the egg to protect it. After fertilization ovary turns into a fruit.

Answer:

The lack of Mad1 protein can cause faster cell division.

Explanation:

The Mad1 protein is responsible for regulating the fixation of chromosomes in spindle microtubules, during cell division. With the presence of this protein, anaphase is prevented from starting while the spindle, where the chromosomes attach, is formed.

Without this protein, this check is not done and cell division occurs faster, which is one of the reasons why cell division can be accelerated.

The cell cycle is the division of cells and the replication of the genetic material. The cell cycle requires 24 hours to complete the cell cycle, whereas some animals complete the cell cycle in 9-10 hours due to a lack of Mad1 proteins.

The correct answer is:

The function of Mad1 proteins are:

Therefore, lack of Mad1 proteins will result in a faster division, because no checkpoint will be available in the anaphase of the cell cycle.

Answer:Essay on Hydrophyte | Plants

Article Shared by  

The below mentioned article provides an essay on hydrophyte.

Hydrophyte embraces all the different and varying plant forms that adapted to live under direct influence of free water or in waterlogged soil, e.g. a small number of ferns and angiosperm. Gymnosperms have not migrated into aquatic habitats.

Hydrophytes, also called hydrophytic plants, are classified according to forms:

Submergent, Floating and Emergent. Submergent hydrophytes grow and remain entirely submerged below the surface of water throughout life. Floating hydrophytes have leaves or shoots that float on top of water surface. Emergent hydrophytes have roots anchored to hydric soil, but a portion of shoot lies above water surface.

The different form of hydrophyte exhibits the following characteristics that help them to survive in water and waterlogged soil:

i. Increase in leaf surface that helps plants for floatation.

ii. The presence of air chambers that assist in buoyancy of the plant.

iii. Stomata, if present, nonfunctional because the plants need not regulate transpiration due to abundance of water in their environment.

iv. Reduction of xylem because the hydrophytes need not conserve water.

v. Reduction in mechanical and protective tissue as water pressure supports them.

vi. Hydrophytes have thin cuticle or lack it. Because the functions of cuticle like protection from strong sunlight, conservation of water and deterrence of insects are not required by hydrophytes. They are protected from excess sunlight by surrounding water; no question arises for water conservation as they have abundant free water in their environment; the hydrophytic angiosperms suffer little predation by aquatic animals.

Due to the thinness of cuticle the leaves absorb nutrients from the water directly. But the major bulk of minerals are absorbed by roots and transported to the leaves. As there is no transpiration pull like land plants the transportation of minerals occur through root pressure. Hydathodes are very common in the leaf tips of many submerged hydrophytes. Transportation of water occurs as a bleeding stream ending in hydathodes. The opening of hydathodes may be large.

vii. Stomata when present may be many in number and occur on upper surface of floating leaves (epistomatous).

viii. Roots are small and reduced in all respects as water can diffuse directly into leaves.

ix. Formation of special roots and these are negatively geotropic and designed to function in gas exchange. Such roots are termed as pneumatophore and present in halophytes.

x. Hydric soils have diluted oxygen and minerals and the hydrophytes adapted to absorb nutrients directly from water.

xi. The piliferous layer scarcely has (or no) root hairs. Root hairs are entirely absent from Ceratophyllum.

xii. The piliferous layer is not cutinized/suberized and so absorptive in function. Moreover the turgid piliferous zone provides mechanical strength, as mechanical cells are absent in hydrophytic roots.

xiii. The cortex of root is wide and provided with air cavities.

xiv. Xylem of root and stem is poorly developed and has thin walls. Vessels are absent in many hydrophytes. In the root of Potamogeton (Fig. 29.9A) the vascular tract in the centre is occupied by a large xylem cavity. The reduction in xylem is due to the fact that in hydrophytes no elaborate system of water absorption is required as all the epidermises of plant body are capable of water and mineral absorption.

xv. The stem of submerged hydrophytes is very weak and flexible. It moves according to the direction of flow of water currents.

xvi. The epidermis in the stem of submerged hydrophytes is uniseriate. It is not cuticularized and in some cases the cells have cellulose walls only. As a result the epidermal cells can absorb mineral salts and gases dissolved in water directly.

xvii. The cortex is wide and has large air chambers. The air chambers may be arranged symmetrically e.g. Myriophyllum (Fig. 29.9B) or scattered irregularly all over the cortex, e.g. Elodea, Hydrilla, Hippuris etc.

xviii. The cells of cortex have low osmotic pressure. The cells contain chloroplastids that help in photosynthesis.

xix. The vascular tissues in stem of submerged hydrophytes are not well developed. Endodermis and pericycle are indistinct. The vascular tissues are mostly composed of phloem.

Hydrophyte

xx. Though the endodermis is not distinct many hydrophytic angiosperms have the innermost layer of cortex that functions as endodermis. This endodermoid layer is present in submerged roots, stems and leaves. It is assumed that this layer is involved in channelizing the flow of water through reduced xylem.

Explanation:

Hydrophytes are aquatic plants that are especially suited for living in aquatic environments.

In order to survive, a hydrophyte, also known as an aquatic macrophyte, must either be completely submerged in water, or in some cases be allowed to float on the surface of the water.

Aquatic plants can usually be categorized into 4 main type: floating plants, deep water plants, marginal plants and oxygenating plants. For a more in-depth description of the various types, please see our page on plants for ponds.

The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants.

Therefore, Hydrophytes are aquatic plants that are especially suited for living in aquatic environments.
