Which of the following statements correctly describes a difference between plant cells and animal cells? a. plant cells have an envelope surrounding the nucleus. animal cells do not.
b. animal cells contain mitochondria. plant cells do not.
c. animal cells contain chloroplasts. plant cells do not.
d. plant cells are surrounded by a cell wall. animal cells are not.

Answers

Answer 1

Answer:

The statement that correctly describes a difference between plant and animal cell is ; ( D )

Plant cells are surrounded by a cell wall. animals cells are not

Eukaryotic cells which includes plants and animals cells have similar characteristics and slight differences. The main difference between a plant cell and an animal cell is the presence of cell wall in plant cells ( for the purpose of rigidity and protection ) and the absence of cell wall in animal cells and this is because animal cells are not rigid in nature and the cell membrane provides protection and shape for the animal cell.

Hence we can conclude that the the difference between the plant cell and animal cell is, Plant cells are surrounded by a cell wall and animal cells are not.

Answer 2

Answer:

Answer:

D) Plant cells are surrounded by a cell wall. Animal cells are not.

Explanation:

Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out, thus animal cells do not have cell walls. So therefore, D is the correct answer.

One difference between carbohydrates and lipids is thata. Lipids will dissolve in water but not carbohydrates.
b. Carbohydrates will dissolve in water but not lipids.
c. Carbohydrates contain hydrogen, carbon, and oxygen and lipids do not.
d. Lipids contain hydrogen, carbon, and oxygen and carbohydrates do not.

Answers

Answer:

B. Carbohydrates will dissolve in water but not lipids

Explanation:

Both carbohydrates and lipids have oxygen, carbon and hydrogen molecules in their compositions.

However, the difference is that carbohydrates are polar and lipids are nonpolar. Nonpolar substances can only be dissolved in nonpolar solvents and so they are insoluble in water (which is polar). Compounds with this feature are called hydrophobic.

Lots of differences, but here's one: Carbohydrates are more rapidly transformed by the body into energy than lipids are. As a result, carbohydrates have a more pronounced impact on insulin levels than lipids do.

A plant appears to grow away from the sunlight and the roots appear to grow deeply straight down into the ground. This plant is displaying which of the following?

Answers

The answer is negatively phototropic and positively gravitropic.

Phototropism is reaction of a plant to a light stimulus. Growth of the plant or its part grow towards the light stimulus is called positive phototropism. Growth of the plant or its part away from the light stimulus is called negative phototropism. Since, the plant grows away from the sunlight (away from the light stimulus), it is negatively phototropic.

Gravitropism is reaction of a plant to gravity. Growth of the plant or its part in the same direction as gravity is called positive gravitropism. Growth of the plant or its part grow in the opposite direction of gravity is called negative gravitropism. The root is positively gravitropic (grows deeply straight down into the ground, in the same direction as gravity).

The cladogram below was created to show the evolutionary relationships between different vertebrates.Which of the following inferences can be made, based on this information?

a. Amphibians and birds share a more recent common evolutionary ancestor than sharks and birds.
b. Birds and sharks do not share a common evolutionary ancestor.
c. Having a bony skeleton did not provide an evolutionary advantage to sharks or ray-finned fish.
d. Rabbits and primates diverged more recently than crocodiles and birds.

Answers

Answer: a. Amphibians and birds share a more recent common evolutionary ancestor than sharks and birds.

Explanation:

A cladogram is a diagrammatic representation of the phylogenetic relationship of recently evolved species with their common ancestors. The relationship is defined on the basis of genetic, molecular, morphological make up of the organisms. The node in the cladogram defines a divergence or difference between the two taxon.

Birds and amphibians share a more recent common ancestor than shark and birds because they can be seen lying closer at the terminal ends of the cladogram.

The answer for the given question above about a cladogram showing the evolutionary relationships between different vertebrates is option A. Amphibians and birds share a more recent common evolutionary ancestor than sharks and birds. I hope this helps.
