Which statements correctly describe herbivores and carnivores?

Biology
1 answer:
dezoksy [38]2 years ago
6 0

Answer:

The First and Third one for sure

Explanation:

Carnivores eat primary consumers as well as other carnivores if I'm not wrong, which would make them secondary or higher consumers.

Also, herbivores eat producers, which are plants and stuff and basically organisms that make their own food, which would make them primary consumers.

You have a 15kb plasmid. EcoRI cuts the plasmid into 7kb and 8kb pieces, and BamHI cuts the plasmid into 1kb and 14kb pieces. If
Harman [31]

Answer:

a. Bands at 1kb, 6kb and 8kb

Explanation:

The EcoRI and BamHI are the restriction enzymes which cut the DNA sequence especially a plasmid at specific sites called the restriction sites.

The restriction enzymes produces bands of specific length therefore these restriction enzymes are used to estimate the approximate length of the DNA.

In the given question, the

1. EcoRI- produces two strands of 7 kb and 8 kb

2. BamHI- produces two strands of 1kb and 14kb

This shows that the length of DNA sequence is 15kb

But when the DNA strand are digested with both the enzymes simultaneously then it will produce three bands as:

i) 14 kb can be broken down in 2 bands of 6 kb and 8 kb

ii) 1 kb band is already produced by the Bam HI.

This shows that 1+6+8= 15 kb

Thus, Option-A is correct.

Put the following events in the correct order:
Wewaii [24]

Answer:

Explanation:

c. Transcription of one DNA strand results in mRNA, which is a complementary copy of the information in the DNA.

a. The mRNA leaves the nucleus and goes to a ribosome open choices for ranking.

b. The building blocks of proteins, are carried to the ribosome by tRNAsAmino acids.

The process of deoxyribonucleic acod starts with replication to transcription and translation.

Replication involves the formation of a complementary base from a old or template DNA Strand this then serve as a template for transcription.

transcription involves the coping of information on the DNA to an intermediate mRNA ( messanger ribonucleic acid) in the nucleus which then move from the nucleus to ribosome in the cytoplasm where translation occurs.

Translation is the conversion of the information on the mRNA to an amino acid with the help of enzyme transferse ribonucleic acid(tRNA).

Hence the arrangement is from C ---- A-----B.

What are polygenic traits controlled by
STALIN [3.7K]

Polygenic traits are those traits that are controlled by more than one gene. Such traits may even be controlled by genes located on entirely different chromosomes. Human height, eye and hair color are examples of polygenic traits. Skin color is another polygenic trait for humans and a variety of other animals
