Question:

Which of these words or phrases are directly related to the mass extinction event that occurred 65 million years ago?

Answer:

<u><em>F. is the only mass extinction event to have occurred</em></u>

Explanation:

Some 252 million years ago, life on Earth faced the “Great Dying”: the Permian-Triassic extinction. The cataclysm was the single worst event life on Earth has ever experienced. Over about 60,000 years, 96 percent of all marine species and about three of every four species on land died out.

Which two statements summarize a way that a self-feeder gets food?
Leona [35]

Answer:

B. Sphagnum moss takes in energy from sunlight.

D. Euglenas carry out photosynthesis.

Explanation:

According to the question, "a self-feeder" means an autotrophic organism i.e. an organism that produces or obtains food by itself. The process by which an autotrophic organism obtains food is referred to as PHOTOSYNTHESIS. Photosynthesis entails the synthesis of food in form of organic compounds in the presence of sunlight.

Based on this, Euglenas, which is a plant-like protist, carrying out photosynthesis and Sphagnum moss, which is a lower plant (bryophyte) taking in energy from sunlight in order to perform photosynthesis are two examples that describes a "self-feeder"

Answer:

Question 1 - c. vv

Question 2 - b. Any of the non-sex chromosomes

Question 3 - b. Eukaryotic

Explanation:

Question 1

As explained, the gene for normal wings (V) is a dominant gene while the gene for the vestigial wings (v) is recessive. Dominant genes overpower any recessive genes.

VV - Two dominant genes will produce the dominant trait

Vv - The dominant gene (V) overpowers the recessive gene (v) and produced the dominant trait.

This means that the only way to have a fly with vestigial wings is if the fly has 2 recessive genes. This means that our answer is c. vv

Question 2

An autosome is defined as any of the non-sex chromosomes.

Question 3

Linear chromosomes are a type of chromosome most often found in eukaryotic cells. On the other hand, prokaryotic cells usually have circular chromosomes. This means that our answer is b. eukaryotic

During glycogenolysis, glycogen is broken down and converted to glucose-6-phosphate, which can enter glycolysis or be used by th
klasskru [66]

1. The enzyme glycogen phosphorylase removes terminal glucose residues from glycogen by cleavinα(1,4) linkages.

2. Enzyme activity stops when the enzyme reaches a point four glucose residues from a branch point, which is an α(1,6) linkage

3. The transferase activity of the debranching enzymes moves three glucose residues to another branch, connecting them by an α(1,4) linkage

4. The <u>glucosidase</u> activity of the debranching enzyme removes the glucose at its<u> α(1,6) li</u>nkage

5. The enzyme <u>glycogen phosphorylase</u> continues removing terminal glucose residue  

Explanation:

Several enzymes are required for the breakdown of a glycogen molecule to a glucose-6-phosphate molecule through glycogenolysis. These enzymes are completely responsible for degrading the glycogen, remodeling the glycogen and converting the glycogen. This is a regulatory process which takes place where is glucose lack or to accelerate fluid. The main enzymes that take part in this glycogen pathway are glycogen phosphorylase and the degrading enzyme.
