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.

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.

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.
