Which of the following explains why meiosis contributes to genetic variations?
A - it increases the ratio of mitosis within an organism
B - It produces offspring that are different from either parent
C - It decreases the rate of mutation occurrence
D - It forms DNA that is resistant to environmental changes

Answers

Answer 1

Answer:

A

Explanation:

Answer 2

The reason of why meiosis contributes to genetic variations is because of option A. it increases the ratio of mitosis within an organism.

Why does meiosis contributes to genetic variations?

Since the recombination and the non-dependent assortment in meiosis, each gamete comprise the different DNA set. It generated the unique combination of genes that should lead to zygote.

Also, it rises the mitosis ratio within an organism

Hence, the option A is correct.

Which of the following is a true statement about lipids in cell members
A. Hydrophobic lipids heads are attracted to water
B. Hydrophobic lipid fatty acid tails turn turn away(repel)from water
C. A bilayer forms when lipid heads turn toward water inside and outside the cell
D. All are correct

Answers

Answer:

it is option B this is correct

Hydrophobic lipid fatty acid tails turn away that is they repel from water as lipids are fat insoluble which are present in cell membrane. Thus, the correct option is B.

What are the lipids in cell membrane?

Lipid molecules are hydrophobic in nature. There are three major classes of membrane lipid molecules including phospholipids, cholesterol, and glycolipids. The lipid composition of the inner and the outer monolayers are different from each other, this reflect different functions of the two faces of the cell membrane.

The most important lipid component of the plasma membrane is Fatty acid. An fatty acid is a monocarboxylic acid with a long generally 14 to 24 carbons long chain, it is unbranched, hydrophobic tail which may be either saturated or unsaturated with zero to six cis, non-conjugated double bonds in the compound. The hydrophobic lipid fatty acid tails turn away or repel from water.

Therefore, the correct option is B.

Are the four daughter cells produced by meiosis identical or unique?

Answers

Answer:

i think it's meiosis identical but im not sure please tell me if it's right or not

Answer:

[tex]\boxed {\boxed {\sf Unique \ daughter \ cells}}[/tex]

Explanation:

There are two main types of cell division: mitosis and meiosis. Mitosis makes identical cells for growth and repair.

On the other hand, meiosis is used for sexual reproduction.

In this reproduction, one diploid cell produces 4 haploid gametes/sex cells, meaning they have half of the genetic information. This is so during fertilization, when a sperm and egg combine, the zygote will have a full set of chromosomes.

One of the most important parts of meiosis is called crossing over. In this step, the chromosomes exchange information and create totally unique chromosomes.

This is one reason why siblings, aside from identical twins, can look similar, but not identical!

Which of the following normally leads to the production of functional messenger RNA in eukaryotic cells?

Answers

Answer: The removal of portions of RNA known as intervening sequences (introns)

Explanation:

The removal of portions of RNA is known as intervening sequences (introns).

What is the process of splicing?

In order to enable the translation of mRNA into a protein, RNA splicing puts together the protein-coding regions (exons) and cuts out the intervening, non-coding segments of genes (introns) from pre-mRNA.

Intron sequences are cut out and exon sequences are joined during the splicing process.

As RNA matures, introns are cut out via RNA splicing, which means that they are not expressed in the resulting messenger RNA (mRNA) product.

In contrast, exons continue to be chemically bound to one another to produce mature mRNA. Exons are expressed sequences, whereas introns can be thought of as intervening sequences.

Therefore, the removal of portions of RNA is known as intervening sequences (introns).

how does the structural adaptation of seeds help them survive​

Answers

Answer:

Explanation:

A seed is a plant embryo wrapped in a protective covering. A fruit is the ripened ovary of a plant which contains one or more seeds.

Most plants are rooted in place, which makes dispersing their fruits and seeds particularly important. Seeds that are spread far from the parent plant avoid competition with their relatives for resources and have the opportunity to colonize new areas. Both fruits and seeds have a variety of adaptations for different types of dispersal.

Examples of the some common types of dispersal follow.

 

Wind

<-- Left : These seeds are transported by air currents. Small fruit or seeds with fine fluff can be carried high up into the air. Herbaceous plants of open areas (like dandelions, cattails, and milkweeds) often have this adaptation. Their seeds float up over neighboring plants even if the parent is growing low to the ground.

Right -->: The fruit of maple trees are also adapted to catch the wind. Many trees (like ashes and sweetgums) have winged fruits or seeds which drop from the tree and are caught by the wind as they fall.

 

Water

<-- Left : Sea bean seeds are adapted for dispersal by ocean currents. Sea bean vines grow along rivers and coasts. When the pods ripen, they split open and the seeds drop into the water. The beans have a thick seed coat to keep the salt-water out, and have internal structures which make them buoyant enough to float. They can drift for hundreds of miles before washing up onto land.

Coconuts (which are single-seeded fruits) are also adapted for water dispersal. Like sea beans, they have a thick shell to prevent the salt-water from damaging the seed, and the buoyant hull keeps the nut floating.

 

Animals: internal transport

<-- Left : Brightly colored fruits advertise for dispersers. They are highly visible to birds, promising a nutritious (and often sugary) reward. The seeds are tough and usually undamaged when eaten. They are dispersed when the bird makes a rest stop.

Right -->: Immature seeds in unripe fruit would die if eaten. The green of young fruit hides them among leaves. Unripe fruit are sour or bitter to discourage animals that do find them. Green fruit cling tightly to the plant, making it hard for animals to remove them.

 

Animals: external transport

<-- Left: Cockle burrs are dry fruit adapted for animal dispersal. The hooked spines catch on the hair (or socks) of passing animals. Dispersal is complete when the animal picks off the offending burr, hopefully dropping it in a new location suitable for growth.

Right -->: Fruit of the unicorn plant have an unusual adaptation for transport. As grazing deer or antelope walk over them, the spines catch around the animals' feet. When the animal finally gets annoyed and shakes the fruit off, dispersal is complete.

What do you mean by meiosis?

Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome.

The purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells. In the figures below, pink represents a genetic contribution from mom and blue represents a genetic contribution from dad.

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.
