Clamworms and earthworms both belong to phylum Annelida. Curiously, earthworms have a thin cuticle outside of their epidermis and clamworms do not. Considering the relationship between an organism's form/function and its environment, which of the following provides the MOST logical explanation for this difference?a. The cuticle maintains salt balance in a marine environment.
b. The cuticle provides protection against predators.
c. The cuticle prevents water loss in a terrestrial environment.
d. The cuticle allows for improved gas exchange.

Answers

Answer: c. The cuticle prevents water loss in a terrestrial environment.

Explanation:

The earthworms have a thin cuticle outside their epidermis. The cuticle performs different functions in the worm body. The cuticle protects the worm from predators. The thin cuticle remains moist with the slimy mucus. The cuticle helps in the exchange of gases from the external environment. The cuticle helps in absorbing the oxygen from the external environment whereas it expels the carbon dioxide to the external environment. The cuticle prevents the loss of moisture and allows the gaseous exchange which facilitates the survival of the worm in a harsh terrestrial environment.

Need help with 13 and 14

Answers

Answer:

13) A

14) I think is A but the question I believe is directly tied to the writing you have

Explanation:

Which two statements explain how the uneven heating of Earth's surfaceaffects Earth's weather patterns?
A. Warm air continuously leaves the poles and moves toward the
oceans.
B. Warm air rises and cool air sinks, forming a convection current
C. Warm air moves away from the equator toward cooler regions.
D. Warm air flows from the northern hemisphere to the southern
hemisphere.

Answers

I am unsure about the actual question,
But if you need to choose two answers, I would do B and C
B; convection currents are responsible for many things like air flow, the amount of humidity, and so much more.
C; Warmer air moves through these convection currents towards cooler regions, which affects the temperature.

The two answers work hand in hand-
So if that is what the question is asking, the answers are B and C

Explanation:

I think it is b because when warm air rises it always affects the earths weather pattetn

What is the maximum number of alleles that a given human adult (with 23 pairs of chromosomes) can have at any particular genetic locus? a. 1
b. 2
c. 23
d. 46
e. There is no maximum number.

Answers

Answer:

b. 2

Explanation:

Humans have typically 23 pairs of chromosomes. Each pair is composed of a chromosome from the mother and another from the father. A specific locus in a chromosome is composed of two alleles. An allele inherited from the mother and the other allele inherited from the father.

What are some of the functions of vascular tissue in seedless plants? (Choose all that apply)provides structural support that allows some lycophytes to grow taller
transports water and minerals
transports food
produces food through photosynthesis

Answers

Vascular tissues can provide support to the plants and also help in the transport of water, mineral and food. So, the correct options are A, B and C.

What is vascular tissue?

Vascular tissues mainly perform the function of supplying all the parts of the plant with water, minerals and food. there are two kinds of vascular tissues - xylem and phloem.

Xylem is the water-conducting vascular tissue. It conducts water from the roots of the plant to various other parts. In the xylem, the movement of water is unidirectional, which means it only conducts water from bottom to top and sometimes sideways

Phloem is the food-conducting vascular tissue of plants. It conducts water from leaves to other parts of the plant. In phloem, the movement of water is bidirectional, which means it conducts water from both directions. Xylem and phloem lie next to each other in a bundle called a vascular bundle.

Lycophytes are a group of seedless vascular plants which have a unique arrangement of their vascular tissues. In these plants, the lycophytes support the growth of plants.

Therefore, the correct options are A, B and C.

Answer:

Explanation:

Xylem transports and stores water and water-soluble nutrients in vascular plants.

Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.

Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.
