b. specialized blood cells
c. a variety of antibiotics
d. toxic enzymes
Help fast please

Answers

Answer 1
i believe the answer is A, weakens pathogens. this is because when you get a vaccine the purpose of it is for your body to fight it and build an immunity to the disease, so the vaccine contains weakened strands of the pathogen so that your body can fight it but not kill itself in the process.

How does exercise change the consumption of oxygen and production of carbon dioxide?

Answers

exercise makes your heart beat faster, which increases the amount of cardiac cycles per minute. this means that you will need to intake more oxygen to keep up with the oxidizing of the blood and as you breathe, diffusion occurs (taking in oxygen and releasing CO2). In short, the more you exercise and the faster your heart beats, the more oxygen you consume and the more CO2 you release.

What weakens hurricanes when they reach the Atlantic Ocean

Answers

colder water churned up from beneath the sea surface by the hurricane can cause the hurricane to weaken.

These storms diminish and disintegrate once they cross over land or across cold water, losing contact with the hot water that gives them strength.

What are hurricanes?

A spiral arrangement of thunderstorms that produce torrential rain and squalls, a low-pressure center, and powerful winds are the characteristics of a tropical cyclone, a fast revolving storm system.

A tropical storm that has sustained winds of 74 mph or greater is referred regarded as a hurricane.

A storm's eye typically measures 20 to 30 miles in width and can reach distances of 400 miles.

Storms can be dangerous because of their torrential downpours, strong gusts, and storm surges.

Because they are no longer being fueled by the energy from the warm ocean waters, hurricanes typically lose strength when they make landfall.

Thus, these are the factors that weakens hurricanes when they reach the Atlantic Ocean.

3. A condition wherein different alleles are present

Answer please

Answers

Answer:

1. phenotype

2. heterozygous

3. homo-zygous

Explanation:

In genetics, phenotype refers to the observable characteristics/ traits in a particular organism. An individual phenotype results from the interaction of genes and the environment. Moreover, in diploid (2n) species, an organism is heterozygous for a given trait when it carries two different gene variants or 'alleles' of the same gene. These two alleles are received from both parents, i.e., one allele from one parent and another one from the other parent. Finally, an organism is homo-zygous for a given trait when it carries two identical alleles of the same gene.

O B. Gel electrophoresis
O C. Recombinant DNA technology
O D. Polymerase chain reaction

Answers

Answer:

C.

Explanation:

The method that uses bacteria to copy DNA is recombinant DNA Technology. To copy the DNA, the recombinant DNA method uses bacteria such as E. Coli whose plasmids are combined with various gene to produce the substance that is wanted.

Polymerase chain reaction uses bacteria to copy DNA.Therefore, the correct option is D.

What is polymerase chain reaction?

Polymerase Chain Reaction is a laboratory technique used to amplify a specific DNA sequence, making many copies of it. The process involves repeated cycles of heating and cooling a reaction mixture containing the DNA template, primers, and a heat-stable DNA polymerase enzyme.

The DNA polymerase enzyme used in PCR is derived from a bacterium called Thermus aquaticus, which can withstand the high temperatures used in the reaction. By copying the DNA sequence multiple times, PCR enables researchers to study and analyze small amounts of DNA, such as those obtained from crime scenes or ancient fossils.Therefore, the correct option is D.

Your bone cells and heart cells contain the exact same DNA but have very different functions. Explain how this i so.

Answers

Answer:

This is so because of GENE EXPRESSION

Please find the explanation below

Explanation:

All living cells including the bone cells and heart cells described in this question are made up of genetic material known as DNA. However, cells of the same organisms contain the exact same DNA, but they perform different functions due to GENE EXPRESSION.

The bone cells and heart cells for example perform different functions because certain genes in the bone cells are expressed while others are inhibited from being expressed. The same goes for the genes in heart cells. In other words, genes are not expressed at the same time, hence, leading to different functions or specialization of cells called CELL DIFFERENTIATION.
