A sort of radiant energy that is visible and moves in waves is light. It is the only type of energy that the human eye is capable of seeing, hence option D is correct.
What is radiant energy?Radiant energy sources comprise the full electromagnetic radiation spectrum, including gamma rays, x-rays, radio frequencies, microwaves, light, and heat radiated by a bonfire.
Light energy is produced by the Sun and other stars, light bulbs, lasers, and heated things, heat coming off of a heated sidewalk. Radiant energy may be found in X-rays.
Any energy produced by the sun is referred to as solar energy, nuclear fusion occurs in the sun and produces solar energy.
Therefore, In the sun's core, fusion takes place when the protons of hydrogen atoms forcefully collide and fuse to form helium atoms, hence option D is correct.

Which statement accurately describes the relationship between air pressure, air density, or altitude?
As altitude increases, pressure increases.
As altitude increases, air density increases.
Air pressure and density are lowest at sea level.
Denser air exerts more pressure than less dense air.
The statement which accurately describes the relationship between air pressure, air density, or altitude is: D. Denser air exerts more pressure than less dense air.
What is air circulation?Air circulation can be defined as the movement and flow of atmospheric air from one point of the equator to another such as North pole to South pole, especially over long distances due to difference in atmospheric pressure.
Generally, atmospheric air that has more density (denser air) would exert more pressure than an atmospheric air that has less density because of a difference in temperature.

The statement that describes the relationship between air pressure, air density, or altitude is "denser air exerts more pressure than less dense air," hence option D is correct.
What is air pressure, and air density?In contrast to the specific volume, which is described in terms of unit mass of dry air, air density is defined as the mass of air per unit volume.
Everything you touch is pressed upon by the weighty air that surrounds you. This pressure is referred to as air pressure or atmospheric pressure.
This is due to the fact that more air molecules are crammed into a given amount of air as density increases.
The force exerted by more air molecules to be greater, and as pressure is the force exerted per unit surface area, it follows that higher density air will experience greater pressure than air with lower density.
Therefore, option D is correct.

What type of consumers are secondary consumers?
Answer:Tertiary consumers eat the secondary consumers and are usually carnivores (meat eaters).Secondary consumers are organisms that eat primary consumers for energy. Primary consumers are always herbivores, or organisms that only eat autotrophic plants. However, secondary consumers can either be carnivores or omnivores. Carnivores only eat other animals, and omnivores eat both plant and animal matter.

Al examinar la aleta de un pez primitivo, los científicos encontraron similitudes entre su estructura ósea y la de los reptiles, las aves y los mamíferos modernos. ¿Que tipos de evidencias describe este caso?
Answer:
evidencia de un antepasado común entre grupos de vertebrados (gnatóstomos)
Explanation:
En el estudio comparativo arriba descripto, se encontraron semejanzas que provienen de un antepasados común. Este tipo de evidencia se conoce como homología, es decir, semejanza entre diferentes grupos de organismos causada por un mismo origen evolutivo. Los gnatóstomos (vertebrados con mandíbula) conforman un grupo de organismos el cual incluye peces óseos, peces cartilaginosos, anfibios, reptiles, aves y mamíferos. En este caso, las extremidades del grupo de los gnatóstomos (las cuales tienen como origen común la aleta de un pez primitivo) son similares porque son estructuras homólogas.

Animal use chlorophyll to produce glucose.
True
False
Animals use chlorophyll to produce glucose. This is a false statement. Hence, the correct answer is second one . Animals are not autotrophs but heterotrophs.
What is photosynthesis?Photosynthesis is a process in which oxygen and glucose are produced from carbon dioxide and water with the help of sunlight in green plants. This reaction is carried out by the green plant because it consists of chloroplasts.
The chloroplast is the organelle that has chlorophyll pigment, and this pigment is responsible for the photosynthesis process. Due to this, plants are called producers. Animals depend upon the plant for food and are called heterotrophs. Animals cannot do photosynthesis.
In different ecosystems, different producers are present, such as in aquatic ecosystems, where algae and seaweeds perform this function. In terrestrial ecosystems, plants perform this photosynthesis. Consumers feed them depending on the producers, and after both the consumer and the producer die, both are decomposed by decomposers.
Hence, animals use chlorophyll to produce glucose; this is the false statement.

Why is the use of stem cells to produce new specialized cells, which can replace a body's damaged cells and cure disease, creating a controversy?
Answer:
human embryonic stem cells are obtained from embryos, thereby they are subject to ethical, religious, political and legal considerations
Explanation:
Human embryonic stem cells (HESCs) are pluripotent undifferentiated cells derived from blastocyst-stage embryos, which have the ability to produce any type of somatic cells. HESCs are obtained in vitro from embryos that are 5-6 days old. These cells are valuable tools in research in order to understand the genetic and physiological mechanisms of human development, as well as to develop treatments against diseases. The use of embryonic stem cells in research is controversial because these techniques involve the destruction of human embryos, and there are people who consider human life begins with the formation of the diploid zygote after fertilization, thereby raising the debate if a human embryo can be regarded as a human being.

In pea plants, tall (T) is dominant to short (t), and green (G) is dominant to yellow (g). Two parents who are heterozygous for both traits are crossed. What are the possible gametes from the parents genotypes? Why do gametes only have one allele per trait?
Remember to use the FOIL method!
You will have 4 possible answers.
Answer:
TG, Tg, tG, tg
Gametes only have one allele per trait because of meiosis. Meiosis is a two-stage process. Before that stage, the cell is diploid, with two versions of each allele. Afterward, only one version of each chromosome gets sent to each daughter cell. Those daughter cells become gametes, and they each have only one version of each allele.
Explanation:
The parents would be TtGgxTtGg because they are heterozygous.
Think of FOIL like this... (Tt)(Gg) and multiply outer and inner

How do you think that wearing personal protective equipment helps to protect us from contracting airborne diseases?
Answer:
Airborne transmission may occur if patient respiratory activity or medical procedures generate respiratory aerosols. These aerosols contain particles that may travel much longer distances and remain airborne longer, but their infective potential is uncertain. Contact, droplet and airborne transmission are each relevant during airway manoeuvres in infected patients, particularly during tracheal intubation.

How is the dispersive model different from the semiconservative model of DNA replication?
1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
2. In the dispersive model, the old double helix is degraded, and in the semiconservative model half of its nucleotides are used in the construction of two new double helices.
3. In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
4. In the dispersive model, one strand of the new double helix is made of DNA, and in the semiconservative model the other strand is made of RNA.
Answer:
It it not, In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
Answer:
option 1 is correct
Explanation:
in dispersive, each strand of DNA has alternating fragments of old and new DNA while in the semiconservative each new double helix consists of one old and one new strand.
