Visible light

Explanation:

Electromagnetic waves are formed from a combination of electrical and magnetic effects. Depending on the wavelengths, there are various waves in the EM waves. One of these waves ranging from wavelength 400-700nm is called VISIBLE LIGHT.

The chlorophyll pigments of plants, which enable them perform the process of photosynthesis, are only able to absorb the visible light of EM waves i.e. light ranging from blue to far red. Hence, VISIBLE LIGHT is the EM wave that is responsible for food production of plants through photosynthesis.

The electromagnetic wave that is important in food production of plants through photosynthesis is visible light.

The electromagnetic spectrum is composed of several waves that have different frequencies and wavelengths. However, the region of the electromagnetic spectrum that lies between 380 to 700 nanometers produce sensations that can be detectable by human eyes hence they are called visible rays.

A pigment is plants called chlorophyll is able to trap light falling on the plant and use it to carry out the combination of water and carbon dioxide to form glucose.

Answer:

Not every member needs to reproduce

Explanation:

I think that not every member needs to reproduce because yiu don't need like a ton of offspring. Take humans as an example. Not every woman wants to have a child but yet we still survive.

A fertilized egg or zygote occurs just after the gamete union happened, at that moment the ploidy of the organism is restored, genetically all the genes are on, this means all are active and at that moment it will start cellular multiplication, now each cellular layer will start to differentiate by turning off certain genes, and genes like Hoax genes will start to guide the body plains, meanwhile in an adult animal no just tigers we have that the full-body plane has been already developed and each cellular line has been differentiated, DNA in every cell is methylated as differentiation already occurred, so even when genetically speaking of DNA the sequence is the same in the zygote as the adult tigger the DNA methylation pattern is totally different, without considering the total biomass increase directed by gene expressions.

In a heterozygous state, one allele masks the effect of another. The allele that is masked is referred to as the recessive allele.

In a heterozygous state, an individual carries two different alleles for a specific gene, one of which is dominant, and the other is recessive. When these two alleles are present together, the dominant allele determines the individual's phenotype, meaning it is responsible for the observable physical traits. The recessive allele, on the other hand, has its effects masked by the dominant allele and does not impact the phenotype. In this situation, the allele that is masked is referred to as the recessive allele.

The recessive allele is only expressed when an individual is homozygous for that allele, meaning both copies of the gene carry the same recessive allele. In a heterozygous state, the presence of the dominant allele prevents the expression of the recessive allele, which remains hidden in the individual's genotype. This phenomenon is known as the law of dominance, one of the principles of inheritance proposed by Gregor Mendel.

In summary, in a heterozygous state, the allele that is masked and does not influence the phenotype is called the recessive allele. This occurs due to the law of dominance, where the dominant allele determines the observable traits of an individual. The recessive allele only becomes expressed when present in a homozygous state.

For a cell to obtain more sugar the cell must use active transport to pump the sugar inside it .

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration which occur against the concentration gradient . So , it requires cellular energy to achieve this action.

Main function of active transport is involves the movement of molecules from a region of lower concentration to a region of higher concentration with help of energy in form of ATP. examples of active transport include the absorption of glucose in the intestine of the human body and the uptake of minerals or ions into the root hair cells of plants.

The affinity of histones for the negative charges on the backbone phosphates of DNA is reduced by histone acetyltransferase, chromatin remodeling complexes, and DNA methylation. The correct option is A.

These processes modify the histones and DNA in various ways, leading to changes in chromatin structure and gene expression. However, histone deacetylase has the opposite effect, increasing the affinity of histones for DNA by removing acetyl groups from histones.

Therefore, the correct answer to the question would be A, C, and D, but not B. The affinity of histones for the negative charges on the backbone phosphates of DNA is reduced by histone acetyltransferase, chromatin remodeling complexes, and DNA methylation.

Explanation:

Nonpregnant women secrete the hormone known as gonadotropin-releasing hormone (GnRH) from neurosecretory cells in the hypothalamus.

GnRH plays a crucial role in the regulation of the reproductive system. It stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland, which then act on the ovaries to regulate the menstrual cycle and the production of estrogen and progesterone.

GnRH is released in a pulsatile manner, with each pulse causing the release of FSH and LH from the pituitary gland. The secretion of GnRH is regulated by various factors, including feedback mechanisms involving estrogen and progesterone levels in the body.

In nonpregnant women, GnRH plays a vital role in maintaining normal reproductive function and the regularity of the menstrual cycle. It is responsible for initiating the growth and maturation of ovarian follicles, the release of the mature egg (ovulation), and the preparation of the uterine lining for potential implantation of a fertilized egg.

The pyramid of biomass is inverted in an aquatic ecosystem because the biomass of fishes far exceeds the biomass of phytoplanktons.

The entire mass of a population of organisms in a particular area is referred to as biomass. A biomass pyramid, in more precise terms, is a calculation of the total mass of the creatures that make up each trophic level of the food chain.

One of the three ecological pyramids is the biomass pyramid:

Calculated by counting the number of species at each level of the food chain, the pyramid of numbers

The pyramid of biomass shows how much biomass there is at each trophic level.

The Pyramid of Energy assesses the energy flow between each link in the food chain, providing the most accurate picture of a community as a whole. Biomass pyramids are typically vertical, with the greatest part at the bottom and the smallest at the top. Inverted biomass pyramids do exist, albeit they are more typical in aquatic environments. Primary producers are always at the base of a biomass pyramid, followed by primary consumers (level 2), secondary consumers (level 3), and so forth all the way to the top.

The curvature in the lower back (lumbar lordosis) helps balance the upper body on the pelvis. In the upper half of the pelvis, the size, shape, and orientation of the iliac paddles differ between apes and humans in a way that reflects our commitment to the walking biped.

In Ardipithecus ramidus it has been tapered and flattened on the sides to support the legs and they also have a shorter and wider pelvis. The three skeletal adaptations that result in a platypelloid pelvis include: an elongated ilium that repositions the gluteal muscles, a shorter distance between the sacroiliac and hip joints, and a ventrally titrated pelvis that aligns the sacroiliac and hip joints. and ultimately produces lumbar lordosis Human bipedalism is promoted by a narrow pelvis. However, in mammals, the pelvis is also the passageway through which newborn babies pass, and the birth canal must be large enough to accommodate a birth. Bipedalism resulted in skeletal changes in the joints of the legs, knees, and ankles, spinal vertebrae, toes, and arms. Most significantly, the pelvis became shorter and rounder, with a smaller birth canal, making childbirth more difficult for humans than other primates.

In incomplete dominance, a heterozygous individual expresses an intermediate phenotype between the dominant and recessive phenotypes. 250 of the offspring are expected to have white flowers.

To answer this question we will assume diallelic gene that expresses incomplete dominance.

Incomplete dominance is an inheritance pattern in which neither of the alleles completely dominates over the other allele.

In heterozygous individuals, the dominant allele can not entirely hide the expression of the recessive allele, resulting in a third phenotype.

This new phenotype is intermediate between the one expressed by the homozygous dominant and the one expressed by the homozygous recessive genotypes.

In the exposed example,

If two pink individuals are crossed,

Parentals) Rr   x   Rr

Gametes) R  r    R   r

Punnett square)   R     r

                      R    RR   Rr

                       r    Rr    rr

F1) 1/4 = 25% of the progeny will have red flowers

     2/4 = 50% of the progeny will have pink flowers

     1/4 = 25% of the progeny will have white flowers

100% of the progeny ------- 1000 individuals

25% white -----------------------X = 2500 individuals

250 of the offspring are expected to have white flowers.

An ichnofossil is any part of the hard skeleton left behind by a vertebrate in the fossil record. This statement is false. An ichnofossil is a trace fossil, which is any indirect evidence of past life, such as tracks, burrows, and feces. It is not part of the hard skeleton left behind by a vertebrate.

Cladograms are scientific hypotheses that can be overturned by new data. This statement is true. Cladograms are diagrams that show the evolutionary relationship between organisms based on various traits. New data can cause changes to be made to cladograms which can result in a change to the interpretation of the evolutionary history of organisms.

Angiosperm plants did not appear until after the extinction of the dinosaurs. This statement is false. Angiosperms, also known as flowering plants, appeared in the fossil record at least 140 million years ago. Although the dinosaurs went extinct around 66 million years ago, angiosperms were already widespread and diversifying by that time.

The definition of an analogous character is "a character that has a similar function to a character in a different organism, but these similarities are due to different evolutionary origins". This statement is true. Analogous characters are traits that have evolved independently in different groups of organisms due to similar environmental pressures and not due to a shared ancestor.

In evolution, non-genetic changes that occur during an organism's life span, such as increases in muscle mass due to exercise and diet, cannot be passed on to the next generation. This statement is true. Non-genetic changes that occur during an organism's life span are not heritable and cannot be passed on to the next generation. Only genetic changes that occur in the germ cells, such as mutations, can be passed on to the offspring.

The definition of a monophyletic group is "a group of organisms that has a single ancestor and contains only some of the descendants of this unique ancestor". This statement is false.
