what does cytoplasm do
Answer: What does cytoplasm do
Explanation:The cytoplasm holds the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also givies the cell its shape.
Answer:
The cytoplasm is responsible for holding the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also responsible for giving the cell its shape.
The 3 major functions of cytoplasm:
The cytoplasm support and suspend organelles and cellular molecules. Many cellular processes also occur in the cytoplasm, such as protein synthesis, the first stage of cellular respiration (known as glycolysis), mitosis, and meiosis. The cytoplasm helps to move materials, such as hormones, around the cell and also dissolves cellular waste.The illustration below shows the steps of meiosis
What is the step that is labeled D?
Answer:
Anaphase
Explanation:
Refer to Animation: Cell Signaling: Adrenaline Signaling in the Heart Muscle. Adrenaline stimulates an increase in heart rate by binding to: G proteins on the cytosolic face of the plasma membrane. adenylyl cyclase. regulatory regions in genes that code for muscle cell proteins. G protein-coupled receptors on the surface of heart muscle cells. nuclear transport proteins that allow adrenaline to be taken into the nucleus to act as a transcription factor.
Answer:
The correct answer is ''G-protein coupled receptors on the surface of cardiac muscle cells.''
Explanation:
Adrenaline is a catecholamine whose pharmacological effects occur at alpha and beta adrenergic receptors. The mechanism of action of all beta adrenergic receptors is the activation of a G protein that activates adenylyl cyclase and increases cyclic AMP production. Adrenaline by b-adrenergic stimulus increases the contractile force of the myocardium (positive inotropic action) and increases the frequency in which the myocardium contracts (positive chronotropic action), consequently there is an increase in cardiac work, with a greater demand for oxygen due to the myocardium to be able to contract. Therefore, the blood flow to the heart is indirectly increased, bringing with it a greater supply of oxygen.

how does secondary succession differ from primary succession? it begins on bare rock or land, it begins where no plants have grown, lichens and mosses form soil first, soil nutrients are already in place
in georgia or in the crib
Answer:
In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
36. Mitosis requires the chromosome to be replicated into______ copies.
a. 2
b. 6
c. 1
Answer:
Option a. "2"
Explanation:
Answer:
Mitosis requires the chromosome to be replicated into 2 copies.
option a is the answer
Explanation:
The cell separates the copied chromosomes to form two full sets (mitosis) and the cell divides into two new cells (cytokinesis). The period between cell divisions is known as 'interphase'.The genome is composed of a number of chromosomes—complexes of tightly coiled DNA that contain genetic information vital for proper cell function. Because each resultant daughter cell should be genetically identical to the parent cell, the parent cell must make a copy of each chromosome before mitosis

QUESTIONZANSY
The cells of a pineapple plant have 50 chromosomes in their nuclei. How many chromosomes are there in the male nucleus in a pineapple pollen grain?
Answer:
25 chromosomes
Explanation:
There are two principal types of cells in the organism: Somatic diploid cells (2n) that reproduce by the process of mitosis, and germ cells that are diploid reproductive cells in charge of gamete production. Germ cells divide by mitosis and meiosis. Through the process of mitosis, they originate more sexual cells, but through the process of meiosis, they give place to haploid gametes, called sperm and egg cells, through the gametogenesis process.
Gametes´destiny is to merge during fecundation, and a new diploid cell called zygote emerges through fertilization. The zygote is a complete cell and suffers successive mitosis to form the new organism.
Meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of chromosomes of the original one.
So, in the exposed example
"...cells of a pineapple plant have 50 chromosomes in their nuclei..."
These might be diploid somatic or germ cells. The number of chromosomes, 2n = 50.
Germ cells in plants suffer meiosis and produce gametes.
Gametes of plants are ovocell and pollen grains. Ovocell is the feminine gamete, while the pollen grain is the masculine gamete.
The pollen grain is haploid and its number of chromosomes n = 25.

Which explanation is best supported by the numbers in the chart?
Answer:
Population of lions are more than cheetahs and zebras.
Explanation:
The chart provides information about the population sizes of Lions, Cheetah and Zebras. According to this information, population of lions is the greatest as compared to Cheetah and Zebras. This is due to suitable conditions for the lions such as food and shelter etc in that jungle of Africa as well as strong competitor and its aggressive behaviour make them successfully survive and increase its population in the jungle.
How is a scientific law different from a scientific theoryWhat is the difference between inorganic and organic compounds?
Answer:
A scientific law predicts the results of certain initial conditions. It might predict your unborn child’s possible hair colors, or how far a baseball travels when launched at a certain angle. In contrast, a theory tries to provide the most logical explanation about why things happen as they do. Organic molecules mainly have covalent bonds whereas, in inorganic molecules, there are covalent and ionic bonds. • Inorganic molecules cannot form long chained polymers as organic molecules do.Explanation:

An object is placed at 0 on a number line. It moves 3 units to the right, then 4 units to the left, and then 6 units to the right. What is the displacement of the object?
Answer:
5
Explanation:
Distance is how far something goes and Displacement is how far it is from 0 or from the starting point. Additionally, displacement is a vector so it has a direction, in this case, left or right. To make this shorter let's just find displacement. So you're at 0 and you go 3 units to the right and so you're at positive 3 on the line. Next, you move 4 units to the left so now you're at -1. Finally, you move 6 units to the right and now you're at postive 5. Now you're +5 units away from 0 and so +5 is your displacement (5 units to the right is also correct)
Answer: +5 units or 5 units to the right (as long as it has a sign or a direction it's correct)

Which definition is the best for “semipermeable membrane
Answer: A semi-permeable membrane is that which only allows certain
substances to pass through.
Answer: A semipermeable membrane is a layer that only certain molecules can pass through. Semipermeable membranes can be both biological and artificial. Artificial semipermeable membranes include a variety of material designed for the purposes of filtration, such as those used in reverse osmosis, which only allow water to pass. The biological membranes of cells are created by two sheets of phospholipid, which contain a lipid tail attached to a polar head. The tail regions of each sheet cluster together, while the heads of the molecules point outward. The polar heads point both outward toward the environment of the cell and inward toward the cytosol. In this way, a hydrophobic region of lipid tails separates the two bodies of solution. This can be seen in the image below.

complementary strand of DNA?
DNA Strand 1: AATCGGTAC
Answer:
TTAGCCATG
Explanation:
Deoxyribonucleic acid (DNA) is a double helix molecule made up of two complementary polynucleotide strands oriented antiparallel to each other. Each nucleotide in both DNA strands is composed of a five-carbon sugar (deoxyribose), a phosphate group and a nitrogenous base. In DNA, there are four types of nitrogenous bases: Thymine, Guanine, Adenine and Cytosine (in RNA, Uracil replace Thymine). According to the base-pairing rules, Adenine always pairs with Thymine through two hydrogen bonds, whereas Guanine always pairs with Cytosine through three hydrogen bonds.
