Answer:

Independent

Explanation:

A density dependent factor would cause a downfall to the population based on its numbers, like a disease. A density independent factor would affect it regardless of the population size, such as a storm or cold winter.

ATP synthase changes ADP into ATP when light energy passes through it. The light-dependent reactions supply the Calvin cycle with CO2 and ATP.

Explanation:

1.65 picogram(s), that expected nuclear dna content of a primary spermatocyte in the same organism.

In a gamete (i.e. sperm or egg), the quantity of DNA is 1c, and the range of chromosomes is 1n. Upon fertilization, each the DNA content material and the range of chromosomes doubles to 2c and 2n, respectively.Because they're produced with the aid of using mitosis, number one spermatocytes, like spermatogonia, are diploid and feature forty six chromosomes.

Each number one spermatocytes is going thru the primary meiotic department, meiosis I, to provide  secondary spermatocytes, every with 23 chromosomes (haploid).A unmarried number one spermatocyte offers upward thrust to 4 sperms after meiosis. Primary spermatocyte undergoes first meiotic department to provide  secondary spermatocytes (haploid). The secondary spermatocytes produce 4 haploid spermatids after the second one meiotic department.

Answer:

Enzymes regulate metabolic processes through a variety of feedback mechanisms including inhibition.

Explanation:

Eukaryotic metabolic regulation refers to the mechanisms by which metabolic anabolic and catabolic pathways are modulated in eukaryotic organisms. Anabolic enzymes are involved in the biosynthesis of molecules, while catabolic enzymes are involved in degradative pathways. Thus, enzymes regulate metabolic pathways by catalyzing chemical reactions at their corresponding rates of reaction. Moreover, feedback inhibition refers to those mechanisms occurring when one enzyme is inhibited by the end product of the metabolic pathway, enabling cells to regulate these products.

Answer:

D)4 haploid cells

Explanation:

Plasma osmolarity, or the concentration of solutes in blood, is the primary factor influencing antidiuretic hormone release.

Osmoreceptor neurons, which sense osmolarity in the hypothalamus, then trigger the release of antidiuretic hormone from the neurons that sense osmolarity. Osmoreceptors do not activate and antidiuretic hormone secretion is reduced when plasma osmolarity falls below a certain threshold. Ever-vigilant osmoreceptors perceive an increase in osmolarity over the threshold as a stimulus to activate the neurons that release antidiuretic hormone. The concentrations of antidiuretic hormone climb sharply and linearly with rising plasma osmolarity, as seen in the figure below.

Antidiuretic hormone release and thirst have an intriguing similarity. Although most likely not the identical ones, both occurrences seem to be triggered by hypothalamic osmoreceptors.

Answer:

The inference is that bacteria can be pathogenic or characteristic of the commensal microbiota of different organs.

Explanation:

The human coexists with commensal micro-flora or commensal biota that are in balance and protect it from other pathogenic microorganisms, that is why we constantly live with a group of bacteria that do not generate pathological conditions in our body and even promote the stimulation of the immune response. .

When this balance is broken, pathogenic or opportunistic microorganisms invade, this is how they proliferate and generate infectious diseases that threaten the balance or state of human health.

Natural selection is one of the evolutive forces. It can select beneficial alleles, which are the product of mutations, and fixate them in the population. Option A. Natural selection.

Natural selection is one of the evolutive forces. It acts by selecting beneficial alleles and increasing their frequency in the population.

It results from the interaction between phenotype and environment, which determines gene destiny in space and time.

Natural selection results in adaptation, meaning that it causes an increase in the aptitude phenotype.      

Aptitude can be defined as the contribution of each genotype to the next generation. Aptitude (or fitness) is reflected by the phenotype that results in the survival, fertility, and capability of having a mate. Aptitude must be significant to the natural selection act in its favor.  

In many cases adaptations, resulting from natural selection can be correlated to environmental factors or selective pressures applied by other organisms or habitats.

The selective agent is the environmental trait that determines the differential survival of the phenotypic classes. The environment influences the probability that each genotype passes its gametes to the next generation.

Individuals exposed to new selective pressures need to adapt to survive. Under these environmental conditions, individuals suffer mutations that lead them to avoid them. Since these mutations are beneficial, they are selected by Natural Selection, fixated in the genotype, and transmitted to the following generations.

Let us remember that a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.

In the proposed situation,

1) ants were exposed to insecticides.

2) probably many of them dies, but some of them mutated and managed to survive

3) since this mutation was benefitial, it was selected by natural selection.

4) ants carrying this mutation got to reproduce and the mutation spread in the population.

The correct option is then A. Natural selection.

Even under high temperatures and low relative humidity conditions, storage life is typically  short time. Calyx freshness was evaluated on a scale from 0 to 2, zero when calyx shows good quality, one when quality remains  acceptable and two if it is no longer acceptable. Storage life is usually brief, even in high temperatures and low ratio conditions, therefore the one strawberry was decayed.

The best time to plant strawberries is within the spring, up to some weeks before the final frost date. You may extend your strawberry crop from late spring to early fall by choosing a variety spread of strawberry types. It takes roughly four weeks for June-bearing types from plant blossoming to fruit picking. Day-neutral and ever-bearing varieties both flower within the spring at roughly the same time and take roughly the same amount of time from flowering to harvest.

Counting on the variety chosen, one strawberry plant will provide 40 to 70 berries throughout the course of the season.  This is often equivalent to fruit weighing between 0.7 and 1.4 kilogram’s (1.5 to 3.0 lbs) in weight. They’re perennial, strawberry plants grow year after year. The lifespan of a strawberry plant is roughly six years, however after the primary two years, fruit production noticeably declines.

Answer:

B)Silent mutation

Explanation:

A Silent Mutation is defined as a point mutation that does not change the amino acid. This occurs because more than one codon can code for the same amino acid. So while the protein was changed in the end there were no large-scale effects to the organism. This is why it is called a "silent" mutation because you cannot tell anything changes and there are no side effects.
