Answer:

In eukaryotic cells, which have a nucleus, the cytoplasm is everything between the plasma membrane and the nuclear envelope. In prokaryotes, which lack a nucleus, cytoplasm simply means everything found inside the plasma membrane.

The cladogram shown below describes the evolutionary relationship among several species, labeled A to F. The five dots represent

(You will find the cladogram in the attaches files)

Answer:

C. The genomes of species C and D are nearly identical because neither species has a derived character.

Explanation:

A Cladogram is a tree-type graph based on cladistic analysis. It represents the common ancestral relationships among the involved groups.

The tree-type graph is a ramified diagram that represents the relationship between the involved taxa.
The cladistic analysis follows the maximum parsimony criterium. Explains the character state from the point of view of the fewest changes through history. Explains evolution with the minimal amount of evolutive changes. It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny.

The sequencing term refers to lists of groups according to their relation. One group is the brother-group of the following one.

So the cladogram represents the relationship between groups according to a derived character.

The derivated character is any trait that a group passes to the descendants. Through evolution, the characters change, and new changes are added. When referring to a derivate character, we mean that all the subsequent species in the cladogram carry the trait.

A cladogram provides an image of how new species keep characters that were inherited from older species.

So, in the exposed example, the five dots represent derived characters, representing traits 1 to 5. Branches A to F, represent groups. (See the cladogram in the attached files). Group A inherited trait 1, group B probably still carries trait 1, but also trait 2. Groups C and D equally inherited trait 3. Group E inherited character 4, and finally, group F inherited character 5.

Groups C and D inherited trait 3 and probably also still have traits 1 and 2. So they are very similar to each other. At a certain point, they diverged, probably due to a new mutation that was not passed to the rest of the group.

C. The genomes of species C and D are nearly identical because neither species has a derived character. Correct.

Why is it so important for scientists to calculate exact amounts of products used by

Vsevolod [243]

Answer with Explanation:

When it comes to the study of the outer space, astronauts play a vital role in giving people significant information regarding their exploration. Most of the missions last for 6 months in space and this is followed by another mission lasting at the same time or so.

When astronauts travel, they need to bring exact amounts of products that they will be using during their expedition. These products are particularly related to personal items that they need in order to survive. However, these items have to be calculated in terms of their weight, since the space craft can only accommodate a certain amount of mass.

The collective term for the personal items is "Personal Preference Kit" or the "PPK." It is said that an astronaut can only carry up to 20 personal items and the total weight should only be 1.5 pounds.

Thus, this explains the answer.

The endocrine system consists of ________

olga_2 [115]

Answer: The endocrine system consists of Glands.

The glands that make up the endocrine system produce chemical messengers called hormones that travel through the blood to other parts of the body. Important endocrine glands include the pituitary, thyroid, parathyroid, thymus, and adrenal glands.

The endocrine system is made up of the endocrine glands that secrete hormones. Although there are eight major endocrine glands scattered throughout the body, they are still considered to be one system because they have similar functions, similar mechanisms of influence, and many important interrelationships.
