Answer:

y the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. ... Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.

Explanation:

30 chromosomes

Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2.

From a diploid germ cell 2n =24 double stranded chromosomes, meiosis will produce four gamete haploid cells n =12 single stranded chromosomes.

Meiosis produces four with half because double stranded chromosomes represents DNA replication. Twice as much DNA as a diploid cell needs.

From a diploid germ cell 2n =24 double stranded chromosomes, mitosis will produce two diploid daughter cells 2n =24 single stranded chromosomes for the same reason.

DNA replication doubles the genome before cell division. Sister chromatids of double stranded chromosomes represent the replicated DNA. During cell division, sister chromatids of double stranded chromosomes are separated into different cells.

Meiosis has two stages, the first separating homologous pairs of double stranded chromosomes, and then the second stage separating sister chromatids into four haploid (n) gametes.

iogann1982 [59]

Answer:

The correct answer is option d) "head-on".

Explanation:

In hunting, the head-on angle refers to a position at which the hunter and the prey are face to face. This shot angle rarely results in a clean kill, ruins a lot of meat, and provides an animal the best opportunity to detect the hunter as the animal is in front of the hunter. At the head-on angle it is harder for the hunter to kill an animal with the first shot and ruins a lot of meat because the animal produces hormones such as adrenaline result of the stress.

An infectious disease researcher isolates the pathogen responsible for an emerging disease. The microbe is grown in the lab. Preparation of the laboratory-grown microbe is treated with a lethal dose of ionizing radiation and then tested for its potential as a vaccine and this is Inactivated type of Vaccine.

<h3>What exactly are pathogens?</h3>

Pathogens include viruses, bacteria, fungi, and parasites that can enter the body and harm the immune system. Among many additional viruses that can lead to serious illnesses are anthrax, HIV, the Epstein-Barr virus, and the Zika virus.

<h3>What is vaccination?</h3>

An easy, secure, and reliable method of preventing hazardous infections before you are exposed to them is vaccination. It boosts your immune system and builds up your body's natural defenses against particular infections.

<h3>Inactivated vaccine:</h3>

In inactivated immunizations, the disease-causing microorganism is eliminated.

Inactivated vaccines typically don't provide as strong of immunity (protection) as live vaccines. Therefore, it can take several doses (booster injections) throughout time to keep up your resistance to diseases.

Using inactivated vaccinations, you can guard against

Flu
Hepatitis A
Polio
Rabies
