Enlist the features of cell membrane.
Answer:
It is the outermost covering of a cell that separates the contents of the cell from its external environment.
It only allows the entry and exit of some materials. It also prevents the movement of some. Therefore, it is also called a selectively permeable membrane.
Some substances like carbon dioxide and oxygen can move across the cell membrane due to the process known as diffusion.
Water also obeys the laws of diffusion. The movement of water molecules through a selectively permeable membrane is called osmosis.

The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

How does anaphase II differ from anaphase I
Answer:
There's a difference.
Explanation:
Anaphase I involves the separating of chromosomes from the sister chromatids and it all occurs in a diploid cell.
Anaphase II involves the split of the sister chromatids into single chromatids and it all occurs in a haploid cell.
Title: Does temperature have an effect on growth rate of crystals? what about leaving them covered or uncovered? Does dry air or moist air seem to grow more crystals
Hypothesis:
IF
THEN
BECAUSE
Help pls
Answer:
Temperature also affects the growth of crystals because "the higher the temperature, the warmer the crystal solution will be, and the faster its molecules will move. This movement allows them to evaporate more quickly, leaving particles behind to form into crystals.
Explanation:
A Warm and Light Atmosphere
Warm air temperature aids water evaporation, causing the crystals to grow more quickly. Crystals will still grow in cooler temperatures, but it will take much longer for the water to evaporate. Crystal growth also requires light.

How can deep density-driven currents affect Earth’s climate?
Answer:
The answer is down
Explanation:
The deep density ocean currents aslo have a strong effect on the Earth's climate the water in the North Atlantic Ocean the water is cold and salty this colder salt water sinks because of its greater density then it flows through Southward deep in the ocean

Answer:
Sea turtles are now facing much greater challenges as a result of climate change. Coastal ecosystems will be eroded and damaged as sea levels rise and storms become more strong. Warming ocean currents could expose sea turtles to new predators while also damaging the coral reefs that some of them depend on to survive.

Mammalian erythrocyte lacks nucleus. Why? Give reason.
Explanation:
Complete answer:
A mature erythrocyte lacks nucleus and mitochondria so as to make a place for the accommodation of more hemoglobin and hence more oxygen molecules. Lack of such organelles also provides the peculiar biconcave appearance of RBCs that aids in efficient diffusion. Young mammalian RBCs are nucleated.

Do it again what is the question about
Answer:
B
Explanation:
Examine the genotype for an individual who is AaBbCcDd. Predict the outcomes of meiosis and the potential gamete combinations
that could form from this individual. Select ALL that apply.
A)
50% of the gametes will be AaBbCcDd.
B)
1/16 of the gametes produced will be ABcd.
The individual could make gametes that contain ABCD.
D)
The individual could make gametes abcd half of the time.
E)
Only dominant traits will be present in the gametes from a heterozygous
individual
Answer: B,C
Explanation:
I did just did the USA test prep
The outcomes of meiosis and the potential gamete combinations that could form from the genotype for an individual who is AaBbCcDd:
B) 1/16 of the gametes produced will be ABcd. C) The individual could make gametes that contain ABCD.A gamete that is formed by the meiosis, is a reproductive cell which has haploid set of chromosomes arise from the genotype, the total number of chromosome in mature organism cells.
A a simple method to calculate the number of gametes:
Count the number of heterozygous alleles i.e Aa Bb Cc and Dd which means 4.n = 4
Then, total number of gametes will be = [tex]2^{n}[/tex] or [tex]2^{4}[/tex] = 16Thus 16 in this condition
The 16 types of gametes are formed by this individual by permutation and combination are:
ABCD, AbCD, ABcD, ABCd,
ABcd, AbcD, ABCd, Abcd,
aBCD, aBCd, aBcd, aBcD,
abCD, abCd, abcd, abcD.
Thus, the correct answer is -
B) 1/16 of the gametes produced will be ABcd. C) The individual could make gametes that contain ABCD.Learn more about permutation and combination:

Most cells in the human body contain two sex chromosomes. Which type
of cell does not have two sex chromosomes?
Liver cell
Muscle cell
Nerve cell
Red blood cell
Answer:
liver cell
Explanation:
The liver parenchyma is primarily comprised of hepatocytes. Hepatocytes are polygonal epithelial cells with abundant eosinophilic, granular cytoplasm and large, centrally located round nuclei. Hepatocyte nuclei often contain a prominent nucleolus. Binucleated hepatocytes (= containing two nuclei) are not uncommon.
