The production of egg and sperm cells follows a certain sequence of events.
Which example lists those events in the correct order?
fertilization, meiosis, cell differentiation
meiosis, cell differentiation, mature gametes
sexual reproduction, cell differentiation, mitosis
cell differentiation, meiosis, sexual reproduction
Answers
The correct order of those events are:
MEIOSIS, CELL DIFFERENTIATION, MATURE GAMETES.
Meiosis is defined as the process wherein a single cell is divided twice to produce four cells that contains half the original amount of genetic information.
Cell differentiation is defined as the process wherein the less specialized cell becomes a more specialized cell. The haploid cells are the end result of meiosis. They must undergo cell differentiation before they can become mature gametes.

How are DNA and chromosomes related?
Answers
A chromosone is a long DNA molecule
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. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
Be able to explain how segmentation and exoskeletons gave some animals an adaptive advantage over those that were not segmented and did not have exoskeletons.
Answers
Answer:
Arthropods have partially alleviated this problem by having the exoskeleton form as individual plates on each body segment or individual cylinders on each segment of the appendages. The plates are called sclerites, and they are connected by flexible tissue to allow the animal to bend during movement.Early land arthropods evolved adaptations such as book lungs or trachea to breathe air. The exoskeleton was another important adaptation. It prevents an animal from drying out. It also provides support in the absence of buoyant water.

What type of succession starts with some soil but then goes through the 10p
steps of succession?
A. Primary Succession
B. Secondary Succession
C. Climax Community
Answers
Explanation:
Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction.[1]
Succession after disturbance: a boreal forest one year (left) and two years (right) after a wildfire.
The community begins with relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable or self-perpetuating as a climax community. The "engine" of succession, the cause of ecosystem change, is the impact of established organisms upon their own environments. A consequence of living is the sometimes subtle and sometimes overt alteration of one's own environment.[2]
It is a phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. Succession may be initiated either by formation of new, unoccupied habitat, such as from a lava flow or a severe landslide, or by some form of disturbance of a community, such as from a fire, severe windthrow, or logging. Succession that begins in new habitats, uninfluenced by pre-existing communities is called primary succession, whereas succession that follows disruption of a pre-existing community is called secondary succession.
Succession was among the first theories advanced in ecology. Ecological succession was first documented in the Indiana Dunes of Northwest Indiana and remains at the core of much ecological science.[3]
Your best friend is concerned about a mole on her arm. Knowing that you are taking a biology class she comes to you and asks for your opinion. You take a sample of her mole and view it under a microscope. While counting a selection of 300 cells, you notice that 87 cells are actively undergoing mitosis. Should your friend be concerned?
Answers
Answer:
She should consult a dermatologist immediately.
Explanation:
When doing preemptive diagnosis of a mole, one should compute the Mitotic Rate (MR) - and the MR reported in the question is way above the highest category "greater than 4 per square millimeter" (to compare. there's around 2000 cells per sqmm of skin, so we're at over 500 per square millimeter).

Explain how the structure of a plant allows it to obtain and keep water.
Answers
Answer:
Most plants absorb water through the roots. Land plants get almost all the water they need from the soil. The amount of water available in the soil varies according to its porosity and its degree of desiccation. A large proportion of water is retained by cohesion forces between the particles. When the water is in the roots it moves inside the plant through the xylem. The xylem is the transport system that carries water to the entire plant.
Explanation:
The xylem connects all parts of the plants (from the roots to the stems and from there to the leaves). The water in the xylem creates a gigantic chain of molecules that adhere to each other, just like they adhere to the xylem. For plants to transport water from roots to leaves and use it in other functions, other structures called stomata are required. Stomata are small pores in leaves that plants can open and close as needed. If they open, the water moves out of the stomata and evaporates into the air. This occurs because the water molecules diffuse, from the humid air inside the leaf, to the much drier air surrounding the leaf. The loss of water through the stomata together with the high cohesion of the water particles and the resistance of the root "stress" the water column. This causes the water potential of the roots to decrease and the surrounding water enters the plant.Each stoma is made up of two occlusive cells. When these cells are turgid, a hole opens between them; when the cells relax, the hole disappears. The turgor pressure depends directly on the inlet or outlet of the water. This movement, in turn, depends on the concentration of solutes within the cell.

a.water is attracted to the sides of a glass cylinder
b.water strider can walk on water

Water is attracted to the sides of a glass cylinder is an example of cohesion.
What do you mean by cohesion?Cohesion means sticking together. If your group of friends heads to the lunchroom as a team and sits all together, you're demonstrating strong cohesion.
Cohesion allows for the development of surface tension, the capacity of a substance to withstand being ruptured when placed under tension or stress.
Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.

Consider the evidence that explains how physical separation of two populations of a species can cause speciation. What effect does physical separation have on organisms that might result in speciation?
Answers
Answer:
Interruption in the genetic flow between separated groupsThe emergence of new mutations in each of the groups, and their accumulation in time. Slow and gradual differentiation between populations. Genetic divergence by natural selection and reproductive isolation Prezigotic isolation mechanismsExplanation:
Allopatric speciation consists of the geographic separation of a continuous genetic background that can give place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flux, as the two new groups that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
The process of allopatric speciation involves different steps that affect organisms:
The emergence of the barrier. Interruption in the genetic interchangeThe occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation. Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears. Prezigotic isolation mechanisms will be favored by selection if occurs a secondary contact between the new species in formation.If a mosquito has 6 chromosomes in each body cell how many chromosomes will each new body cell have after mitosis?

What are Prokaryotes?A prokaryote is a single-celled creature without a nucleus and other membrane-bound organelles he Greek words pro and v (pro, meaning "before") are combined to form the word prokaryote.
Prokaryotes were categorized under the empire Prokaryota in the two-empire system developed by Édouard Chatton. However, prokaryotes are split into two domains in the three-domain concept, based on molecular analysis:
Bacteria (formerly Eubacteria) and Archaea (previously Archaebacteria). The third domain, Eukaryota, is designated for organisms containing nuclei. Prokaryotes are thought to have evolved before eukaryotes in terms of biology.
Therefore, They absorb nutrients directly from the environment.

A researcher conducted studies on proteins obtained from mouse livers. He discovered a novel protein and decided to study its genetic origins. During his tests, the researcher found the mRNA sequence AUUCGGUACUGUACUAGC. What is the DNA sequence that was used for synthesizing this mRNA sequence?
Answers
Answer:
TAAGCCATGACATGATCG
Explanation:
Transcription is the process of transfer of genetic information from DNA to RNA, typically to a messenger RNA (mRNA). During transcription, a particular DNA sequence called 'gene' is used as template to create an mRNA which is subsequently used to synthesize a protein by the process of translation. During this process (transcription), Uracil (U) bases pair with Adenine (A) and replace thymine (T) bases in RNA.
