Answer: The correct answer is respiratory route.

Explanation: Disease can be transmitted from human to human through respiratory route. This can occur when the infected person cough or sneeze into the air , some particles of the pathogens are released and there is any human around the infected person when he sneez or cough, the person tend to get infected by inhaling or breathing in the infected air.

Answer:

a. The hog farmer does not notice the barn smell from the working boots when he  wears them on the porch of the house.

Explanation:

The hog farmer does not notice the barn smell from the working boots when he  wears them on the porch of the house is the example of sensory adaptations. Sensory adaptation is a decrease in sensitivity to a stimulus after regular exposure to it. So the farmer can't smell his own boots due to regular exposure to the smell so we can say that it is an example of sensory adaptations..

Answer:

The correct answer is -pernicious anemia

Explanation:

Pernicious anemia is a deficiency of erythrocytes or the red blood cells due to by vitamin B12 deficiency in the blood. Of an individual. It could be understood by vitamin 12 deficiency that caused by impaired uptake of vitamin B-12 due to the lack of a substance known as intrinsic factor (IF) produced by the stomach lining.

Answer:

This question lacks options, the options are:

A. 1

B. 3

C. 6

D. 11

The answer is C. 6

Explanation:

pH of a solution refers to the concentration of hydrogen ions in that solution. A scale is used to measure pH of a solution.

* A pH value less than (<) 7 is said to be ACIDIC. The lesser the number, the more acidic

* A pH value of exactly 7 is said to be NEUTRAL

* A pH value above (>) 7 is said to be BASIC OR ALKALINE. The higher the number, the more alkaline.

According to this question, two solutions of equal volume with pH values of 2 and 12 respectively were combined. Based on the explanation of pH scale, the solution with pH 2 is said to be very ACIDIC while the solution with pH 12 is said to be very ALKALINE.

Hence, if this two solutions are combined, a neutralization will occur which will result to a solution with close to neutral pH (7). In the above options, 6 is the closest pH value to NEUTRAL and hence, the most likely pH of the resulting solution.

Answer:

coexistence is possible if each species is more efficient at using a different resource than the other species.

Explanation:

Competition is an ecological and evolutive process very common in nature. Competition might be intra- or interspecific. Competition between different species in a community or ecosystem might be due to the same resource use, or the same territory, shelter, etcetera. When a resource is useful for two or more species, and limited, they compete to gain it.

The principle of competitive exclusion states that different species with the same requirements sharing the niche can not coexist indefinitely based on the same limited resource. When two competing species coexist, this is because of niche partitioning or niche differentiation.

Differentiation of effective niche is closely related to character displacement.

Character displacement is the result of interspecific competition, in which two or more species that live in the same habitat manage to avoid competition by developing different traits. Morphological divergence, or any adaptative trait development, fixated genetically, is the product of niche segregation. Species tend to differentiate morphologically in the presence of strong competitors. Traits divergence favors coexistence in the same place.

In the exposed example, both species have different abilities to utilize different levels of multiple resources. If both species live in the same place, this ability is significant to avoid competition and competitive exclusion.

Answer:

ATP

Explanation:

Answer:

See the answer below

Explanation:

The phenomenon is best explained by the fact that the genetic codes are degenerates. In other words, more than one codon can specify for the same amino acid being carried by the tRNA.

The base-pairing rule between the third nucleotide of a codon and that of the anticodon on the tRNAs loosens off. For example, GUU, GUC, and GUA all specify for the amino acid valine while GCU, GCC, and GCA all specify for alanine.

Answer:

2nd one is correct

Explanation:

Answer: B

Explanation:

the child has the blood type of Ab its obvious

Explanation:

only when both alleles is O, the blood group can be O. Thus both parents must have O as one allele

Thus man's genotype: BO or

[tex] { | }^{b} i[/tex]

Woman's genotype : AO or

[tex] { | }^{a} i[/tex]

When

the children can not have O blood

The children cannot have B blood

means the man have BO

[tex] { | }^{b} i[/tex]

and woman have AA

[tex] { | }^{a} { | }^{a} [/tex]

Because

if man have BB, and woman have AA

children can only have AB

if man have BB, and woman have AO

children can only have AB and B

Answer: Oval.

Explanation:

The nucleus of a cell is a membranous structure normally found in the center of eukaryotic cells and is where most of the cellular genetic material is found, organized in DNA molecules (deoxyribonucleic acid) associated with proteins such as histones, which make up the chromosomes.

The function of the nucleus is to maintain the integrity of the genes in the DNA and to regulate gene expression to control cellular activities. It then controls when DNA is transcribed into RNA (ribonucleic acid) and when it is exported to the cytoplasm to be translated into proteins.

The nucleus is composed of a nuclear envelope consisting of a double membrane that surrounds it, as well as pores that allow the passage of RNA for the regulation of gene expression.

The cells of the inner cheek are classified as non-keratinized stratified squamous epithelium. An epithelium is a tissue made up of joined cells that line the outer surface of the body and inner organs. Squamous cells are flat, scale-like, whereas stratified cells are arranged in multiple layers. Non-keratinized means that the cells constitute soft tissue found in the moist parts of our body, such as the mouth, stomach, among others. In a normal healthy cell, the nucleus is uniformly stained, oval in shape and smaller in relation to the cytoplasm.

Answer: Gram-positive bacteria.

Explanation:

Gram-positive bacteria are those bacteria that stain dark blue or violet by Gram staining. This is due to the structure of the cell envelope, since they possess a cell wall composed of a thick layer of peptidoglycan, which surrounds the previous one. The cell wall is attached to the cytoplasmic membrane by lipoteichoic acid molecules. The peptidoglycan layer confers high resistance to these bacteria and is responsible for retaining the stain during Gram staining. Unlike gram-positive bacteria, gram-negative bacteria have a second lipid membrane outside the cell wall and a single peptidoglycan layer.

An antibiotic is a chemical substance produced by a living being or synthetically derived, which kills or prevents the growth of certain classes of sensitive microorganisms, such as bacteria. An antibiotic could be bacteriostatic if it prevents the growth of bacteria or bactericidal if it destroys them.

Antibiotics usually attack cell walls, such as β-lactams that act on the peptide chains of the bacterial cell wall. That is, they act by inhibiting peptidoglycan synthesis. This is why gram-positive bacteria are susceptible to certain types of antibiotics because they possess a large amount of peptidoglycan.

Answer:

not enough skin exposure to the sun to make Vitamin D.

Explanation:

The correct answer would be not enough skin exposure to the sun to make Vitamin D.

The body makes vitamin D by being exposed to the sun and this vitamin and its metabolite are quite important in the homeostasis of calcium. Calcium on its own is very essential to the formation of bones in the body.

Hence, when the skin is not adequately exposed to the sun, the body becomes short of vitamin D and this disrupts the homeostasis of calcium and the formation of bones in the body. Thus, osteoporosis, also known as weak bones, may result.

Answer:

(A) not enough skin exposure to the sun to make Vitamin D.
