Answer:

The suspect might be guilty, but more information is needed from other parts of the investigation.

Explanation:

Due process states innocent until proven guilty. Having an 80 percent chance of deception is not solid proof of anything. It does, however, bring more speculation to the table that this person is indeed guilty, but because there is no actual proof, the investigators must find more information on the matter.

Answer:

a).Don't know if you meant to write 3x10^10km and 2x10^10km

I'll solve with this... If they aren't the values... You can then input the real values.

Distance = Total length traveled.

D= 3x10^10 + 2x10^10

D= 5x10^10Km

b) Displacement:

Since it went vertically... Then went horizontally in the second phase... It is forming a right angled Triangle and the Displacement would be the Hypotenuse of this triangle.

Disp.= √ (3x10^10)²+(2x10^10)²

Disp.=3.61x10^10km.

advantages:Physical barriers play an important role in preventing microbes from reaching tissues that are susceptible to infection. At the cellular level, barriers consist of cells that are tightly joined to prevent invaders from crossing through to deeper tissue.

Physical barriers play an important role in preventing microbes from reaching tissues that are susceptible to infection. At the cellular level, barriers consist of cells that are tightly joined to prevent invaders from crossing through to deeper tissue.

Immune system is a large network of organs, white blood cells, proteins (antibodies) and chemicals. This system works together to protect you from foreign invaders (bacteria, viruses, parasites, and fungi) that cause infection, illness and disease.

Disadvantages of physical barriers in the immune system is causing immuno deficiency disease.

So, to highlight it, table salt or food salt that humans consume are inorganic compounds.

Answer:

The correct answer is - Ploidy is the number of sets of chromosomes in a biological cell.

Explanation:

Ploidy is the number of sets of the chromosome in a living cell. Ploidy is known for different condition such as haploid, diploid, and aneuploid, and many more depends how many homologues chromosome numbers are present in the cell.

Diploid cells are common in many organisms where one chromosome come from the mother gamete and the other from the father gamete and makes the homologues chromosomes. In diploid homologues, chromosome are 2n where n is the number of homologues of each chromosome.

In haploid there is only one set of each chromosome and mainly takes place by meiosis. In aneuploidy is the condition where the number of homologues chromosomes are not as the normal genome of the organism for example in humans instead of 46 chromosomes there 45 or 47 chromosome found.

answer : Permeable Rock layers allow the flow of fluid like substances through them, While Impermeable rock layers do not allow the flow of fluid like substance through them.

Explanation:

Permeable rocks are rocks containing pores through Fluid like substances can penetrate through in the rocks. examples of Permeable rocks are ; Sandstones and Chalk

While an Impermeable rock is a rock that does not allow the flow of fluid like substance through it due to the absence of pores in its rock layers . examples of such rock are ; Clay and marble  

Although some permeable rocks might exhibit low level of permeability as well but generally Rock sample with pores are classified as permeable rock layers.

Answer:

Explanation:

The missing diagram in the question is attached in the image below.

(A)

From the image below, the frequency of occurrence is shown in the last column.

The frequency of occurrence means the particular band for the entire whole population.

As an example:

1 in 15 frequency of occurrence means; ⇒ One (1) out of every fifteen (15) people has the band.

1 in 450 frequency of occurrence means; ⇒ One (1) out of every 450 people has the band.

(B)

However, Let the probability that Joe and Sam are twins be = A

and the probability that they are not twins be denoted with B;

Then;

P(B) = 1 - P(A)

where;

P(A) = Probability of specific bands appearing on the gel in every one of them

[tex]P(A) =\Big( \dfrac{1}{15}\times \dfrac{1}{15}\Big)\times \Big( \dfrac{1}{450}\times \dfrac{1}{450}\Big)\times \Big( \dfrac{1}{32}\times \dfrac{1}{32}\Big)\times \Big( \dfrac{1}{70}\times \dfrac{1}{70}\Big)[/tex]

[tex]P(A) =\Big( \dfrac{1}{225}\Big)\times \Big( \dfrac{1}{202500}\Big)\times \Big( \dfrac{1}{1024}\Big)\times \Big( \dfrac{1}{4900}\Big)[/tex]

P(A) = 4.37 × 10⁻¹⁵

∴

P(B) = 1 - P(A)

P(B) = 1 - 4.37 × 10⁻¹⁵

P(B) ≅ 1

Answer:

4 percent (4%)

Explanation:

A single crossover occurs between two (non-sister) chromatids belonging to homologous chromosomes. In this case, 16 percent of the meioses have a single crossover, thereby it will produce 8 percent of the chromosomes with the original (parental) combination in the progeny and the remaining 8 percent should be recombinants. From this result, it is reasonable to conclude that half of these recombinants should be 'Br' (and the other remaining 4 percent should be recombinants 'bR'), and therefore the answer is 4 percent (4%).

Answer:

Fishes use a different vision mechanism than mammals and other land animals. They have rods and cone photoreceptors to see the colorful visions and adjust their focal point by moving the lens closer to or away from their retina.

In the water bodies, a difference in the amount of light moves with the depth because water absorbs the light and this change occurs due to the optical nature of water.

The light bounces once it back in the retina, leads to the gain of the small packets of energy of light a second chance to be trapped by photoreceptors. However, vision remains blurry. The changes and distortion of the light-absorbing molecules present in the eyes of fishes make it tough to perceive a clear vision.

Explanation:

Answer:

The correct answer is - decreased population size at all levels.

Explanation:

A decrease in the productivity of producers of an ecosystem will lead to a decrease in all other organisms of the ecosystem including top-level consumers to the bottom-level producers due to the fact that producers provide energy and food to primary consumers.

It is because they are the only organisms that convert the sunlight to usable energy and food that transfer from one trophic level to other, so if the population of producers or their productivity will decrease then there will be decreased population size at all levels.

Answer:

a. True

Explanation:

An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.

Basically, the endocrine system contributes significantly to the state of homeostasis in the body.

Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.

Homeostasis is maintained through feedback mechanisms, which are either positive or negative feedback.

During a negative feedback, a sensor and a control center in the body of a living organism maintains blood glucose to regulate blood pressure by releasing glucagon to increase blood sugar or releasing insulin to decrease blood sugar.

For a positive feedback, a sensor and a control center aids child birth by causing the uterine to contract.

Being able to plan in advance for a genetic disorder in a child is an advantage for a parent who sees a genetic counselor. So, the correct option is (B).

A genetic disorder is a type of disease caused in whole or in part by a change in a DNA sequence away from the normal sequence.

It can be caused by several reasons like

1. Monogenic Disorder

It is caused by a mutation in one gene

2. Multifactorial Inheritance Disorder

It is caused by mutations in multiple genes

3. Combination of gene mutations and environmental factors.

4. Damage to chromosomes by the changes in the number or structure of entire chromosomes, the structures that carry genes.

Genetic counseling helps parents for better understand test results and treatment options, helps deal with emotional concerns, and provides referrals to other healthcare providers and advocacy and support groups.

Thus, being able to plan in advance for a genetic disorder in a child is an advantage for a parent who sees a genetic counselor. So, the correct option is (B).
