Explanation:

Answer: The correct option is D.

Genes are made of DNA and code for proteins.

Explanation:

This is because genes contain the genetic information needed for expression of characteristics in a living organisms. Therefore, genes contain DNA which is the genetic material. Genes are housed in chromosomes located in the loci.

DNA molecule forms a chromosome, and part of the same DNA molecule produce the genes on that is found in that chromosome. The information that is present in each gene codes the production of proteins and alsothe synthesis of RNA.

Answer:

Helix

Explanation:

Answer:

The DNA molecule is a polymer of nucleotides. Each nucleotide is composed of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group. There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine). A DNA molecule is composed of two strands.

Hope this helps

Answer:

This is because in biology, energy is transferred from organism to organism and some energy is lost along the way. Each energy transfer results in a loss of energy, so that energy is always at a lower level and can never be returned to its original high energy level. On the other hand, chemical elements can form products, then that reaction can be reversed and break back down into reactants. Additionally, the law of conservation of matter says that matter can't be created or destroyed, only transferred from one form to another.

Answer:

C

Explanation:

Energy flows while matter cycles

Oil spills, polluting factories and power plants, raw sewage, toxic dumps, pesticides, freeways, the loss of wilderness and the extinction of wildlife

In certain organisms, like humans, there are two morphologically distinct types of gametes: (1) the male gamete (i.e. sperm cell) and (2) the female gamete (i.e. ovum). The male gamete is smaller in size and motile whereas the female gamete is several times bigger and non-motile. The haploid condition of the two gametes is essential so that at fertilization during sexual reproduction the integrity of the chromosomal number is maintained throughout generations.

Hope this helps.

Answer:

Examples of Gametes. The two most common gametes are sperm and ova. These two haploid cells can undergo internal or external fertilization and can differ from each other in size, form, and function. Some species produce both sperm and ova within the same organism

Answer: Biochemical engineers conduct studies on cells, proteins, viruses, or other biological substances to determine optimal conditions for growth or inhibitors that can stop or kill. They develop and conduct experiments to observe interactions of raw materials with each other and in specific environments.

Answer: An increase in gene flow between the bird populations.

Explanation:

The population of bird species living in the island and other one in mainland are geographically isolated because of the distance between the island and the mainland is large that does not allow birds to fly and cover the entire distance. This is the reason of reproductive isolation and restricts the gene flow between the two populations. But the creation of sandbars and tiny islands between the island and mainland created a way so that island and mainland birds can meet and reproduce. This will allow the increase in the gene flow between the two separated population of bird species.    

Answer:

unicellular ....... sorry there's a 20 character requirement

Answer:

unicellular is the right answer

Answer:

Explanation: Well, In the first few days after a fracture/breakage in the bone, the body forms a blood clot around the broken bone to protect it and deliver the cells needed for healing. Then, an area of healing tissue forms around the broken bone. This is called a callus, (It joins the broken bones together)

Answer:

The elongation process.

Explanation:

There are 3 stages in translation/protein synthesis:

Mupirocin works by inhibiting one of the tRNAs. Specifically, it inhibits the tRNA carrying an amino acid known as isoleucine. Thus the translation process is disrupted and the protein synthesis truncated. In other words, mupirocin works by cutting short the elongation process of translation.

The stage of translation that is directly affected by mupirocin is the elongation process.

What is Translation?

The process by which a cell makes proteins using the genetic information carried in messenger RNA (mRNA).

Mupirocin is an antibiotic that is used to treat skin infections. It basically prevents the bacterial species to grow on our skin. The Mupirocin inhibits the tRNA that carries amino acid isoleucine. Therefore, the translation process gets affected and the synthesis of protein is trimmed. Mupirocin specifically functions as bypassing the elongation process of translation.

Thus, the stage of translation that is directly affected by mupirocin is the elongation process.

Answer:

Guy on top is correct. It is 100%

Explanation:

As predicted by the Punnett square, 100% of the offspring have black fur for this cross.

When two individuals with the genotype BB (homozygous dominant for black fur color) are crossed, their Punnett square will look like:

 | B  | B  

--|----|----

B | BB | BB

--|----|----

B | BB | BB

All the offspring will have the genotype BB, which means they will be homozygous dominant for black fur color. Therefore, all the offspring will have black fur.

Answer:

In nature, the logistic growth model is more common.

Because interaction between species and the environmental conditions needed for an exponential growth model are not always possible. In fact, they are hardly possible.

Explanation:

This model states that there is unlimited resource availability. As there are guaranteed resources and space, there is no competition. Population growth does not depend on density, nor Natality and mortality rate. There is constant growth, which is proportional to the population size. The exponential growth model is represented by an exponential curve.

In nature, this is almost impossible. Just a few organisms, such as bacteria species, might be represented by this model. But in most species, this is not feasible because available resources are not infinite, space is not infinite, and there is always an interaction between species that affects their population sizes.

When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population's per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

K is a constant that coincides with the size of the population at the equilibrium point when the natality rate and the mortality rate get qual to each other.  

The logistic growth model is represented by a sigmoid curve. In the beginning, the population grows slowly. Its size N is inferior to K.In the second stage, the population size increases rapidly but N, is still inferior to K. Gradually, the population reaches the equilibrium point, K, which depends on resource availability. N equals k.  Resources become harder to find, and much of the living space is unavailable. Finally, when N is superior to K, the population must decrease in size because there are not enough resources to maintain that size.      

Species have different strategies to survive in different environments, reproduce, disperse, and compete. These strategies are r strategies and k strategies.  

"r" species: Their growth rate per capita is very high, which makes possible the colonization of new environments. These species are mostly small-sized organisms with short life cycles. They reach sexual maturity at early stages and have numerous offspring. They hardly spend energy in parental care. Many "r" species exhibit the exponential growth model, but not all of them.        

"k" species: Their growth rate per capita is low. They are often big-sized and long-lasting species.  They reach sexual maturity in advanced stages and do not have numerous offspring. They spend much time of their lives in parenting to ensure reproductive success. They are important competitors, being capable of displacing other species and monopolizing the available resources. "k" species exhibit the logistic growth model.
