Answer:

True

Explanation:

The correct option about the arrangement of the body layers to be dissected in a dissection study from superficial to deep is ; TRUE

During dissection study there only one way in which structures can be viewed  also when the body layers are to be dissected are arranged  in only one way as well ( from superficial to deep ) because the superficial layers lie just under the skin while deep layers lies deep inside the skin surrounding each muscle.

therefore arranging the body layers from superficial to deep is the best arrangement when dissecting.

Answer:

Yes.

Explanation:

Yes, conclusions can be drawn from the types of habitats the most microbes likely to present because different microbes needs different types of environmental conditions. Some microbes needs moist and cool environment and can't survive in warm and dry environment while some microbes survive in dry and warm environment and die in moist and cool environment so we can draw conclusion from their habitat types.

Answer:

Co-dominance.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

In Genetics, co-dominance can be defined as a phenomenon in which two (2) alleles of the same gene are present in a living organism and both are equally expressed to a degree or simultaneously.

This ultimately implies that, co-dominance is a phenomenon that typically involves the relationship between alleles i.e the two (2) versions of a gene present in living organisms. Also, a single version of a gene expressed by a living organism is referred to as an allele.

In this scenario, when shorthorn red cattle are bred to shorthorn white cattle, they produce roan (red and white hairs interspersed) offspring. Therefore, this type of inheritance is known as co-dominance because the two (2) alleles (shorthorn red and shorthorn white) are expressed equally or simultaneously in their offspring i.e a roan.

Answer:

if the population is too high and food is scarce.

high population attract predators.

high competition for food.

mutations.

Answer:

A reduction over time in a region's population can be caused by sudden adverse events such as outbursts of infectious disease, famine, and war or by long-term trends, for example sub-replacement fertility, persistently low birth rates, high mortality rates, and continued emigration.

Answer:

(Bad idea)

Many people are against the idea of extending the DNA database because of the potential threat it has to our privacy. While a DNA profile provides very little information about someone, their DNA sample contains information that can reveal their ethnicity or how susceptible they are to disease. The risk of data abuse is therefore potentially high.

(Good idea)

A DNA database of everyone may make it easier for police to identify missing people and unidentified remains.

I found a good article that is helpful for your paragraph. It supports both sides. It wont let me link so just type in :  

"Is it ethical to have a national DNA database?" and it should be the first article that pops up

Answer:

why we should

Every American should give their DNA sample so then its easier, takes less time and so police can move on to other more important cases. Taking samples of DNA from all Americans would dramatically improve law enforcement's efficiency. Thousands of people have been convicted because suspects can be searched out across space and time based on DNA evidence. Hundreds of innocent people have also been freed, often after years behind bars, sometimes just short of the death penalty.

Why we shouldnt

Taking every single american dna will take a long time and will take alot of money and resources. And sometimes your genetic information could be sold to the highest bidder. And sometimes The results are often inaccurate.

i couldnt find more reasons why we shouldnt so you should go over why we should section more

Answer:

c.Cytosine and uracil

Explanation:

Two types of Nitrogenous bases(heterocyclic aromatic molecules) are found in DNA and RNA: 1.Pyrimidines and 2.Purines

Pyrimidines:Thymine(5-methyl-2,4-dioxypyrimidine) and Cytosine(2-oxy-4-aminopyrimidine) are found in DNA .  Uracil (2,4-dioxypyrimidine) and Cytosine (2-oxy-4-aminopyrimidine) are found in RNA.

Purines:Adenine (6-aminopurine) and Guanine(6-oxy-2-aminopurine) are the two purine bases that are found in both DNA and RNA.

Answer:

The mitotic spindle attaches to the kinetochores at the centromeres of the chromosomes and then it moves toward the poles of the cell. Thus, sister chromatids are separated simultaneously at their centromeres so that each daughter cell will have the same genetic material as the parent cell (i.e., daughter cells will be genetically identical to the parent cell).

Explanation:  

The mitotic spindle is a structure composed of microtubule proteins whose function is to ensure the correct segregation of the chromosomes during mitosis. During metaphase, microtubules from the mitotic spindle bind to the kinetochore (a protein complex assembled on the centromeric region) in order to align sister chromatids on the metaphase plate. Subsequently, during anaphase, the mitotic spindle moves toward the poles of the cell, thereby sister chromatids are separated from each other. In consequence, each daughter cell will have the same amount of genetic material (i.e., the same number of chromosomes) as the parent cell.

Answer:

The mosquitos have distinctive characteristics since they have diverse proteins for body measure highlight in their cells. Contrasts within the structure of protein atoms influence how they associated with other protein atoms. A quality form gives enlightening for making a particular protein, so mosquitos with distinctive combinations of quality adaptations will have distinctive proteins in their cells that result in little, medium, or huge body sizes. Each parent haphazardly passes on one of its two duplicates of quality for a include, which is why each mosquito sibling can have a diverse combination of quality forms indeed in spite of the fact that they have the same guardians.

Answer:

B

Explanation:

In sound navigation and ranging (SONAR) the sound wave is transmitted through water and it will reflect by hard surfaces, hence option b is correct.

Sonar is used to create nautical charts, find underwater navigation hazards, search for and map things on the seafloor such as shipwrecks, and map the seafloor itself, waves are transmitted into the water and reflected by hard surfaces.

The transmission and receiving of sound waves are involved in active sonar. For example, when a submarine is used to map the topography of the ocean floor.

it emits sound pulses, known as pings, towards the bottom of the ocean in its area Sound is transmitted through the water and hard surface reflection.

Therefore wave interaction in sonar is sound is transmitted in water and reflected by hard surface, hence option b is correct.

Answer:

A. light penetration

Explanation:

Water clarity refers to how clear a water is, and it is a measure of how far/deep light can penetrate into such a water body. A water that is not clear is said to be TURBID. Several factors affect the clarity of a water body and they include;

- Phytoplankton, which refers to floating algae on the water body. An accumulated growth of phytoplankton can affect the penetration of light into the water, hence, making the water unclear.

- Suspended sediments can also block the penetration of light into the water, reducing water clarity.

- Nutrients in form of fertilizer or waste materials can also make water unclear.

Therefore, LIGHT PENETRATION DOES NOT IMPACT WATER CLARITY, rather it is dependent on water clarity.
