Explanation:

Monocots contain a single cotyledon in their seed and dicots contain two cotyledons. The nutrients in the endosperm of dicots is absorbed by the two cotyledons. Therefore, a tiny endosperm is found inside the dicot seed. However, the main difference between cotyledon and endosperm is in their function during seedling.

Explanation:

Answer :

Climate change intensifies this is cycle because as air temperature increases, more water evaporates into the air. Warmer air can hold more water vapour, which can lead to more intense rainstorms, causing major problems like extreme flooding in coastal communities around the world.

Answer:

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.

Answer:

Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the basis of their cellular characteristics. For example, prokaryotic cells lack a nucleus and other membrane‐bound structures known as organelles, while eukaryotic cells have both a nucleus and organelles. Prokaryotic and eukaryotic cells are similar in several ways. Both types of cells are enclosed by cell membranes (plasma membranes), and both use DNA for their genetic information.

Prokaryotes include several kinds of microorganisms, such as bacteria and cyanobacteria. Eukaryotes include such microorganisms as fungi, protozoa, and simple algae. Viruses are considered neither prokaryotes nor eukaryotes because they lack the characteristics of living things, except the ability to replicate (which they accomplish only in living cells). Viruses - Corona virus, HIV.

Explanation:

The dominant phenotypes are expected to occur at a frequency of approximately 75%, in a population because of its dominant nature which allows them to appear in the physical structure of the organisms. In most of the offspring, the dominant allele shows their characteristics in the population whereas the recessive allele are hidden in that organisms and we can't see them in the physical appearance of the organisms.

This is an epidemic form of conjunctivitis which almost always affects both eyes. The patient may complain of a foreign body sensation, with watering, discharge, redness, and swelling of the lids. They may also complain of the eyes being sensitive to light, with blurred vision.

Answer:

Different colour occur due to heterozygous nature.

Explanation:

Most of the puppies just like parents because the black colour gene or allele is dominant over other colour allele whereas other colour puppies also formed due to presence of heterozygous type of alleles. Other colour occurs due to appearance of recessive allele in the physique of the offspring or formation of hybrids occurs which causes colour other than black and white in the offspring. In the F1 generation all the offspring resembles to the male parent but after this generation some offspring resembles to male, some are hybrids and other resembles to female.

Explanation:

The function of ATP IN living organisms is that ATP is stored in all the cells for energy of all cells.

ATP captures the chemical energy by digesting food particles, breaking it down to deliver into the

cell process enough to disperse ATP throughout the bloodstream for energy to every cell of the body, to work properly in digestion, releases it to fuel all cells in the body, this is the last process for fuel in the cell system in the digestive process..

Answer:

This ice layer insulates the water below it, allowing it to stay liquid, which allows the life within it to survive. If ice sank, the liquid water on top would also freeze and sink, until all the liquid water became frozen. Water is less dense as a solid, than as a liquid, which is why ice floats.

Answer:

Iron deficiency leads to low hemoglobin levels, and therefore oxygen levels are lower than normal  

Explanation:

Hemoglobin is a protein found in red blood cells whose main function is to transport oxygen to the tissues. Anemia is a condition caused by iron deficiency, which is a micronutrient required for red cells to produce hemoglobin. When hemoglobin levels in red blood cells are low due to iron deficiency (anemia), then levels of oxygen in the blood are also lower than normal. In consequence, iron deficiency may cause that cellular tissues don't have sufficient oxygen to carry out their functions.

Explanation:

Answer:

Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.

Explanation:

The end products of mitosis are two identical daughter cells, while on the other hand, the end products of meiosis are four sex cells. Meiosis is the cell division that is responsible for the presence of "recessivity" of genes in organisms because meiosis type of cell division occurs in the gametes of the organisms such as sperm and eggs. This cell division allows the gametes or allele appears in the organisms that is dominant and hide the features of recessive allele.

Answer:

The expected double recombinant frequency = 0.0402 = 4.02%

Explanation:

Available data:

→ Two genes that are very close will have a few recombination events and are strongly bounded.

→ The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant one.

1) First, we need to know their order in the chromosome, and to do so, we need to compare the distances between them.

The most distant pair is a-pr

----a---------------------------------------------pr---

    ║-------------------44,7 MU-------------║

From  gene a to vg there are 32.2 MU

----a-----------------------------vg--------------pr---

    ║-------------------44,7 MU-------------║

    ║----------32.2 MU------║

Finally, de distance from vg to pr is 12.5 MU

----a-----------------------------vg--------------pr---

    ║-------------------44,7 MU---------------║

    ║----------32.2 MU------║--12.5 MU--║

We can name region I to the distance between a-vg, and region II to the distance between vg-pr.

2) To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cM. And that the maximum recombination frequency is always 50%.

1 MU -----------1% of recombination

32.2 MU -----X =  32.2 % of recombination

12.5 MU-------X =  12.5 % of recombination

3) The expected double recombinant frequency = recombination frequency in region I x recombination frequency in region II.

The expected d. recombinant frequency = 32.2%  x  12.5% = 0.322 x 0.125

The expected double recombinant frequency = 0.0402 = 4.02%
