What feature of a phylogenetic tree shows a group of organisms that evolved from a common ancestor
A)host
B)tree
C)clade
D)Branch

Answers

Answer
D) branch
Explanation

The feature of a phylogenetic tree that shows a group of organisms that evolved from a common ancestor is known as a Clade. Thus, the correct option for this question is C.

What is a Phylogenetic tree?

A phylogenetic tree may be defined as a type of diagram or representation that illustrates the lines of evolutionary descent of different species, organisms, or genes from a common ancestor. This is made on the basis of evolutionary relationships.

A clade may be characterized as a type of taxon that significantly consists of all the evolutionary descendants of common ancestors. While branching represents the process of speciation from common ancestors on the basis of certain facts.

Therefore, a clade is the feature of a phylogenetic tree that shows a group of organisms that evolved from a common ancestor. Thus, the correct option for this question is C.

While frying some eggs on a frying pan, a friend points to the change that happens to the egg white, which contains a protein called albumin. Your friend explains that if the conformation of a protein changes, it will no longer have the same properties and will lose its ability to function. Do you agree or disagree with your friend? What happened to the albumin?
EXPLAIN

Answers

Answer:

Yes because when subject to high heat, the proteins change into varying proteins, which is a chemical change. The heat causes denaturation of the albumin, which hardens and causes the change in color. The protein, when heated, untangle and they will mesh. This will trap the surrounding water, and cause the change in color.

Explanation:

The innermost compartment of a mitochondrion is filled with a matrix. It is the site for the Krebs cycle. Here the pyruvic acid is broken down into carbon dioxide.

What is the Krebs cycle?

The primary source of energy for cells and an essential component of aerobic respiration is the tricarboxylic acid (TCA) cycle, sometimes referred to as the Krebs or citric acid cycle. The cycle converts the acetyl coenzyme A (acetyl CoA) chemical energy into the reducing force of nicotinamide adenine dinucleotide (NADH).

The TCA cycle is a component of the broader glucose metabolism, which involves the oxidation of glucose to produce pyruvate, which is then further oxidized and reaches the TCA cycle as acetyl-CoA.

The cycle's half of intermediates also serves as the starting point for pathways that lead to significant molecules such as fatty acids, amino acids, or porphyrins. The integrity of the cycle is compromised and the cycle ceases to operate when any of these intermediates are so diverted. Only if the deflected intermediate or a succeeding intermediate that contributes to oxaloacetate can be replaced by anaplerotic (refilling) processes can vital energy production be restarted.

Therefore, the innermost compartment of a mitochondrion is filled with a matrix. It is the site for the Krebs cycle. Here the pyruvic acid is broken down into carbon dioxide.

A student observes that a plant has droopy leaves and stems and infers that the rate of photosynthesis has slowed in the plant. Which statement provides evidence to support the student's inference?

Answers

Answer:

The water pressure in the plant's vacuole is low, and without water, the chloroplasts  cannot convert carbon dioxide to glucose during photosynthesis.

Explanation:

The water pressure in the plant's vacuole is low, and without water, the chloroplasts  cannot convert carbon dioxide to glucose during photosynthesis. The water pressure in the plant's ribosomes is low, and without water, the chloroplasts  cannot convert carbon dioxide to glucose during photosynthesis. The water pressure in the plant's vacuole is low, and without water, the mitochondria  cannot convert carbon dioxide to glucose during photosynthesis. The water pressure in the plant's ribosomes is low, and without water, the mitochondria cannot convert carbon dioxide to glucose during photosynthesis.

The correct answer would be that the water pressure in the plant's vacuole is low, and without water, the chloroplasts  cannot convert carbon dioxide to glucose during photosynthesis.

Photosynthesis generally requires water as one of its reactants in the formation of carbohydrates for plant nutrition.

[tex]6CO_2 + 6H_20 --> C_6H_1_2O_6 + 6O_2[/tex]

The process takes in the chloroplast of green plants. Without adequate water which is usually stored in the vacuoles of plant cells, the conversion of water to carbohydrates would reduce or cease totally.

Answer: The question is incomplete and the options are not given, here are the options from another websites.

A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts

cannot convert carbon dioxide to glucose during photosynthesis.

B. The water pressure in the plant's ribosomes is low, and without water, the chloroplasts

D. The water pressure in the plant's ribosomes is low, and without water, the

mitochondria cannot convert carbon dioxide to glucose during photosynthesis.

With which cellular process are ribosomes directly involved?

The correct option is C.

Explanation:

When a plants vacuole has no pressure and water, the leaves and stems will drop because vacuole is an organelle that serve as storage for food nutrients and water . When a plant has no water for a long period of time, the vacuole will lose water, which will make the cell to lose shape, and the leaves and stems will wilts and drop ,and this make the mitochondria not to be able to convert chemical energy in glucose using carbondioxide and water to Energy or ATP because there is no supply of water or there is water lose.

Suspended in the fluid stroma of chloroplasts are
a.
cristae that provide energy.
numerous mitochondrial membranes.
b. stacks of thylakoids called grana. d. organelles called eukaryotes.

Answers

Answer:
Stacks of thylakoids called grana

Explanation:
Thylakoid is site of light dependent reaction which will provide material for dark reaction(Calvin cycle) to occur in the stroma

Stacks of thylakoids called grana are suspended in the fluid stroma of chloroplasts. Therefore, option (B) is correct.

Plants and other chloroplast-containing organisms transform sunlight into chemical energy through photosynthesis. The fluid stroma in plant cells' chloroplasts helps this process. The gel-like stroma surrounds the thylakoid membranes.

Chlorophyll-containing chloroplast thylakoids are membrane-bound. Light-dependent processes, the first stage of photosynthesis, collect light energy with these pigments. Grana boost light absorption by stacking thylakoids

In light-dependent reactions, thylakoid membrane chlorophyll molecules absorb light energy. ATP and NADPH, which are needed for the next stage of photosynthesis, are produced from this energy.

The fluid stroma around the thylakoid membranes includes enzymes, chemicals, and ions for dark processes and the Calvin cycle. ATP and NADPH from thylakoids convert carbon dioxide into glucose and other organic molecules in the Calvin cycle. Therefore, option (B) is correct.
