Which is the best definition of a prokaryotic cell? It has a cell wall but lacks a well–defined nucleus and organelles, and its cytoplasm doesn't have much structure.It contains a membrane–bound nucleus and organelles, and its organelles have specialized duties.
It contains a membrane–bound nucleus, a large central vacuole, a cell wall, a cell membrane, and chloroplasts.

Answers

Answer 1

Answer: Options:
it has a cell wall but lacks a well–defined nucleus and organelles, and its cytoplasm doesn't havemuch structure. - this is the correct one!

It contains a membrane–bound nucleus and organelles, and its organelles have specialized duties.
no!, this is false! prokaryotes don't have membrane-bound nucleus!

It contains a membrane–bound nucleus, a large central vacuole, a cell wall, a cell membrane, and chloroplasts.- no!, this is false! prokaryotes don't have membrane-bound nucleus!

so, for this we only needed to know that prokaryotes DON'T have a membrane-bound nucleus (and this is also perhaps their most important property)

The cladogram shows relationships among several mammal species. Which group of modern mammals is the most closely related to elephants?

Answers

From a cladogram, elephants mammals of the family Elephantidae and from a cladogram under the order of Proboscidea. Also, from the cladogram, we can see that Proboscidea are closely related to Hyracoidea. Among the modern mammals, Hyrax is the most appropriate one which has some characteristics similar to elephants. Hyrax is a herbivous mammal, also called dassies, which is under the order of Hyracoidea.

The word hetero means different. Since the rocks are varied i assume it would be a heterogeneous mixture.

Squamous cells are part of _____ tissue and are _____ shaped.epithelial; irregularly
connective; cube
nervous; column
epithelial; cube

Answers

The terms that correctly completes the sentence 'Squamous cells are part of _____ tissue and are _____ shaped' are epithelial; irregularly. Squamous cells are part of epithelial tissue, and thus they can be found on the surface of the skin and the lining of body organs. Their shape is irregular. They are thin and flat cells and remind on fish scales.

Answer: The correct answer is Epithelial; Irregular

In garden peas, the allele for tall plants is dominant over the allele for short plants. A true-breeding tall plant is crossed with a short plant, and one of their offspring is test crossed. Out of 20 offspring resulting from the test cross, about how many should be tall?A. 5
B. 20
C. 10
D. 0
E. 1/2

Answers

Answer: Option C

Out of the 20 resulting offspring of the test cross, 10 (50%) will be tall.

Explanation:

Let True-breeding tall plant be "TT"

Let short plant be tt

On crossing, all offspring will be "Tt"

Test cross involves the breeding of an individual with a phenotypically recessive individual. The test cross of offspring "Tt" against "tt" will then yield an equal ratio (1:1) of Tt to tt.

Thus, out of the 20 resulting offspring of the test cross, only 10 (50%) will be tall.

Final answer:

When a true-breeding tall pea plant is crossed with a short plant, all the F1 offspring will be heterozygous tall. Upon performing a test cross of a heterozygous F1 tall plant with a short plant, about half of the resulting offspring should be tall. Thus, out of 20 offspring, approximately 10 (Option C) should be tall.

Explanation:

In garden peas, the allele for tall plants (T) is dominant over the allele for short plants (t). A true-breeding tall plant has two copies of the dominant allele (TT), while a short plant has two recessive alleles (tt). When you perform a test cross between a heterozygous tall plant (Tt) and a short plant (tt), the results should theoretically yield a 1:1 ratio of tall to short offspring. Since the question states the tall plant is true-breeding and crossed with a short plant, all offspring from this initial cross would be heterozygous tall (Tt). Each of these offspring, when test crossed with a short (tt) plant, would produce tall and short offspring in a 1:1 ratio.

Therefore, out of 20 offspring from the test cross, approximately half should be tall and half should be short. So, the expected number of tall offspring would be about 10.

The correct answer to the question is option C- 10.

Which statement about stomata is true?A.)The number of stomata is greater on the upper surface of the leaf.

B.)The number of stomata is greater on the lower surface of the leaf.

C.)The number of stomata is equal on both surfaces of the leaf.

Answers

The answer is B. The number of stomata is more on the lower surface of the leaf. The primary function of the stomata is to regulate moisture loss from the plant. The upper surface of the leaf is more exposed to the air and sunshine thus water is more susceptible to evaporation. However, the stomata is abundant on the lower surface, the location of it helps the plants to conserve more water

What is the relationship between coronary artery disease and a heart attack?Coronary artery disease is a symptom of heart attacks.
Heart attacks reduce blood flow to the heart and cause coronary artery disease.
Coronary artery disease can reduce blood flow to the heart and cause heart attacks.
Heart attacks occur when coronary artery disease is treated.

Answers

coronary heart diseases occur when the arteries are blocked with fatty deposits
so there is less blood flow to the heart. less oxygen and nutrients to the heart. this leads to heart attack. coronary diseases lead to attacks
