<h2>The Genome Sequences</h2>

Explanation

Answer (d) is right answer.because the prokaryotes into two domain is the difference in genome sequences.

The two prokaryote spaces, Bacteria and Archaea, split from one another Archaea are likewise different, however none are pathogenic and many live in outrageous conditions.
Prokaryotes are genuinely more straightforward cells than eukaryotes, and their genomes are a basic, single hover of primarily coding successions of DNA, which is repeated and coded into proteins quickly.
Archaea flourish in various limits such as heat, cool, corrosive, base, saltiness, weight, and radiation.
These diverse ecological conditions after some time have permitted Archaea to develop with their outrageous surroundings so they are adjusted to them and, actually, make some hard memories adapting to less extraordinary conditions.
Most extremophiles are microorganisms (and a high extent of these are archaea), however this gathering additionally incorporates eukaryotes, for example, protists (e.g. green growth, parasites and protozoa) and multicellular life forms.
Archaea is the fundamental gathering to flourish in outrageous situation

Answer: Option D

Explanation:

Prokaryotes are unicellular organisms that lack nucleus and membrane bound organelles. Prokaryotes are divided into two dormain because of differences in genetic make up. They are divided into Bacteria and Archaebacteria.

This is because there are differences in their genetic makeup, they do not have the same materials in their cellular cell wall. Bacteria have peptidoglycan in their cell wall but Archaebacteria don't have.

Because connective tissue is found throughout the body, more than just anne marie's joints and skin could be affected by ehlers-

Art [367]

Fasciae are layers of connective tissue, mainly collagen, situated under the skin, which closes, supports, and separates muscles and other structures. Fasciae are grouped by their anatomical location, layer (as visceral fascia, superficial fascia, and deep fascia), or by their functions. Fasciae reduces friction and provide an adjustable covering for nerves and blood vessels as they move through muscles.

Image result for What is considered a Growing ovary

Your Care Instructions. Ovarian growths are abnormal growths in or on the ovaries. The growth can be a cyst, which is a fluid-filled sac, or a mass (neoplasm), which is a more solid growth. Most of these growths are not cancerous (benign) and don't cause symptoms.

Please help I can’t figure this out

Ilia_Sergeevich [38]

Answer:

Photosynthesis is the process in which cells use carbon dioxide and water to make glucose in the presence of sunlight.

Respiration is the process in which glucose molecules are utilized to release energy in the form of ATP.

Explanation:

Ans1- Respiration in cells occurs in mitochondria. Cells gain energy in the form of ATP. Conversion of glucose in the form of ATP is known as cellular respiration.

Cellular respiration can take place either in presence of oxygen(aerobic respiration) or in absence of oxygen(anaerobic respiration ).

Before entering into cellular respiration glucose molecule has to be converted into pyruvic acid. This process in known as GLYCOLYSIS.

Anaerobic respiration occurs in mitochondria when oxygen is not present. It is known as fermentation.It is not effective process to produce ATP from glucose as in this process only 4 ATP can be released.

Aerobic respiration occurs in mitochondria in presence of oxygen. This is effective pathway to gain ATP as it releases 36 ATP from 1 glucose molecule.

Ans2- All cells which has photosynthetic pigments are able to use photosynthesis. Example- Blue green algae, cynobacteria etc.

Ans3- We can see different shades of green colors of plants and leaves because of different types of chlorophyll present in plant. Chlorophyll are of 6 types in plant. Their types are based on the lights they absorb. Two main types of chlorophylls are chl a and chl b.

Ans4- Both plant and animal cells have mitochondria. In plant also they need energy. To get ATP from breakdown of glucose respiration is occur in plant also.

Ans5-In photosynthesis glucose is formed from water and carbon di oxide. 6 carbon dioxide and 6 molecules of water are used to make 1 molecule of glucose. Water and carbon di oxide are reactant in this process.

Ans6 - Cells without oxygen can burn glucose to release energy. This process is known as Anerobic respiration/ fermentation. But the outcome of energy is lower than aerobic respiration. ( ANS1)

Ans7- In the process of photosynthesis reactants are water and carbon di oxide. Oxygen produced released in the form of gas along with carbon di oxide.

Ans8- The enzymatic reaction of respiration occurs in mitochondria. Krebs cycle occurs in the matrix of mitochondria.( ETC electron transport chain) to release ATP occurs in cristae of inner membrane of mitochondria.

Ans9- Plants make glucose through photosynthesis . In presence of sunlight plants use carbon dioxide and water to make sugar.

Differences between arteries, veins and capillaries

matrenka [14]

Answer:

There are three main types of blood vessels:

1)Artery ---

i) It is a blood vessel having a thick wall.

ii) It carries blood from the heart to different parts of the body.

iii) On regulatory demand of the body it can dilate or constrict.

iv) It doesn't contain any valve.

v) All arteries carry oxygenated blood except the pulmonary artery.

2)Vein ---

i) It is a blood vessel having a thin wall.

ii) It brings blood from different parts to the heart.

iii) It can't dilate or constrict under normal conditions.

iv) It contains valves that allow the blood to flow in one direction towards the heart.

v) All veins carry deoxygenated blood except the pulmonary vein.

3)Capillary ---

i) It is a very narrow blood vessel that has very thin walls.

ii) It forms a network throughout the body in all living cells connecting arteries to veins.

iii) It can dilate or constrict according to the requirement of tissue.

iv) It doesn't have any valve.

v) It contains mixed blood as it connects arteries and veins
