Answer:

an investigator will often use a black light to scan an area for traces of bodily fluids left at the crime scene. if there’s a substance that resembles semen or blood, they will often times apply a spray if it is dry and use a cotton swab to collect it in a vial to test back at the lab for dna evidence.

Assume that the mother's genotype is AZ/az, and the father's genotype is Az/aZ, and the recombination rate is 10%. What are the
Varvara68 [4.7K]

Answer:

.45 from mom, .05 from dad

Explanation:

Given that:

the mother's genotype is AZ/az

i.e AZ = 50%

az = 50%     (parental)

But  we  were also told that the recombination rate is 10% which will like wise affect the mother's genotype

So 100% -10% = 90 % of the mother's genotype

We have a new genotype

AZ = 45%

az = 45% (parental)

Therefore the probability of az gamete from the mother = \frac{45}{100}

= 0.45

Similarly; the genotype of the father is:  Az/aZ

This is an heterozygous father who is diploid hence, there is a remarkable presence of two copies of each autosomal chromosome.

Az is the allele of the genes in one chromosomes and aZ is the allele of the genes in the other.

The gametes of this self cross are: Aa, AZ, az, zZ

Therefore; the recombinants are:

AZ

az

Since there are 10% recombinant; then

AZ = 5%

az = 5%

Therefore the probability of az gamete from the father = \frac{5}{100}

= .05

Global climate change is the result of increasing levels of carbon dioxide, methane, and other greenhouse gases in Earth's atmos
jok3333 [9.3K]

Answer:

Answer in Explanation

Explanation:

Before we proceed to explain the relation between the two, we need to understand what these terms are.

Acidification of the ocean simply refers to an increase in the acidic content of the ocean due to increased level of dissolved carbon iv oxide.

When we talk of climate change, we are talking about the overall and continual change of the atmospheric conditions of the Earth.

The reason why there is a climate change increase is because the atmosphere which is supposed to serve as a sink for green house gases is not serving this purpose and as such there is a retention of the green house gases such as carbon iv oxide within the sun-atmospheric level on the earth.

These green house gases such as carbon iv oxide which does not find a way out of the earth’s atmosphere will be retained in bodies within the earth crust serving as a sink for them. An example of this sink is the ocean which thus takes in the carbon iv oxide which when dissolved increases the acidic content of the ocean causing acidification

Which type of respirator delivers clean air to the breathing zone from a tank worn by the operator?
MissTica

An air-purifying respirator that employs a blower to pump air through filters or cartridges and into the user's breathing zone is known as a powered air-purifying respirator, or PAPR. In comparison to a powered or negative-pressure half mask, this generates a positive pressure inside the facepiece or hood, increasing protection.

<h3>What kind of respirator offers a separate source of clean air?</h3>

For entry into or exit from settings regarded as IDLH, Self-Contained Breathing Apparatus (SCBAs) are employed. They can be either open circuit or closed circuit and contain their own breathing air supply.

<h3>What 2 categories of respirators exist?</h3>

Air-purifying and supplied-air respirators are the two main categories of respirators. Respirators that purify the air remove airborne pollutants such particles, dangerous vapors, and/or gases. They are suitable for use in surroundings with low levels of pollution and in areas with enough oxygen.

<h3>When should you use an air purifying respirator?</h3>

a small, unproven area. a lack of oxygen in the atmosphere. Firefighting. Contaminants with a lower explosive limit (LEL—the concentration at which a gas or vapour could ignite) of at least 20%
