Where is most of the baryonic matter (ordinary matter) of the universe found?

A. in planets and natural satellites
B. in comets and asteroids
C. in dark matter and dark energy
D. in interstellar gases and stars

Answers

Baryonic dark matter may occur in non-luminous gas or in Massive Astrophysical Compact Halo Objects, and stars. So therefore it’s D.

Most of the baryonic matter (ordinary matter) of the universe is interstellar gases and stars. Baryonic matter is the visible matter. Thus, the correct answer is D.

What is Baryonic matter?

Visible matter is also known as the baryonic matter. It consists of baryons which are subatomic particles such as protons, neutrons and electrons.

In cosmology, baryonic dark matter is the dark matter composed of baryons. Only a small proportion of the dark matter in the universe is likely to be baryonic the rest of the matter is all dark matter. Baryonic matter only includes matter composed of baryons.  It can be described as the baryons are made up of protons, neutrons and all the objects composed of them (i.e. atomic nuclei), but exclude other things like electrons and neutrinos.

Therefore, the correct answer is D.

what is photosynthesis​

Answers

Answer:

photosynthesis​ is the cycle of plants using sunlight water and carbon dioxide.

Answer:

Photosynthesis is the process in which carbon dioxide, sunlight, and water gets turned into energy (glucose) by plants, and the plant releases byproducts (oxygen) back into the air.

Explanation:

Inside the plant is a small organelle (a little body inside a cell dedicated to a certain job) called a chloroplast. When a plant is in sunlight, it gets absorbed into the chloroplast and converted into energy by the chloroplast. While the plant is absorbing sunlight, it is also taking in CO2 (Carbon Dioxide), H2O (Water) and minerals from the soil to help in the process to generate energy.

give correct procedure of activities carried out in an experiment to investigate soil drainage​

Answers

Explanation:

These are 5 inverted cut bottles with different soils:

(Gravel, Sand, Loam, Clay, and Peat)

- The piece of cloth is tied at the mouth of the bottle to let out water at the same rate as the piece of cotton wool in the previous diagram.

- Soil that is very porous holds very little water and therefore allows too much water to pass through it.

- From the above, gravel has very large particles,it allows too much water to pass through it meaning it holds little water.

- Peat has more fine particles than Clay Soil, hence holds more water than Clay. It therefore allows very little water to pass through it.

what is to be searched for is a scientific knowledge of essences in contradistinction to a scientific knowledge of facts?

Answers

Answer and Explanation:

Scientific knowledge must always be focused on the search for facts and not essences, since they are the facts that manage to expose the functioning and composition of elements that are directly or indirectly interacting with human beings.

This is due to the fact that scientific knowledge is knowledge produced through tested and proven evidence, which is able to answer a question based on evidence, that is, the nature of scientific knowledge is the exposure of facts. Thus, we can affirm that, there is no scientific knowledge established in essences, because essences are subjunctive elements, impossible to be tested and proven.

How is your body temperature held constant despite different weather temperatures
outside?​

Answers

Answer:

Core body temperature The body can only stay at a constant temperature if the heat generated is balanced and equal to the heat lost. Although the core temperature must be close to 37°C, fingers and toes can be colder. This is because energy is transferred from the blood as it travels to the fingers and toes.

Answer: When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.

Hereditary information is passed from one generation to the next. Which two processes are responsible for the passage of hereditary information from generation to generation in mammals, birds, reptiles, fishand other animals?
A.Meiosis and fertilization B. Mitosis and fertilization C. Mitosis and Meiosis
D. Asexual reproduction and sexual reproduction

Answers

Answer: c

Explanation:

Meiosis and fertilization, two processes are responsible for the passage of hereditary information from generation to generation in mammals, birds, reptiles, fish and other animals.

What is meiosis and why is it important?

Meiosis occurs in chromosomes which allows the production of haploid germ cells necessary for seˣual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.

Fertilization restores the diploid number of chromosomes, that is 46 in human being. It provides stimulus for the ovum to complete its maturation.

An area surrounded by tall mountains contains a very large, isolated population of green and white peacocks. During the mating season, the male peacocks demonstrate flashy feather displays to attract females, who usually choose green peacocks over white ones. A biology student tabulates the following information.

Genotype

Plumage Color % of Population Allele Controlled Phenotype
FF or Ff
Dark green

84%

F (dominant)

Dark green plumage

ff
White

16%
f (recessive)

White plumage
Using this information, the student plans to use the Hardy-Weinberg equation to predict the allele frequencies in future peacock generations. Why would her research advisor have a problem with this? (2 points)

Group of answer choices

The student needs the percent of the population with the Ff genotype in order to find the F frequency.

Her research advisor would first want her to find the males' mating success rate for the calculations.

The peacocks are sexually selective when choosing mates, so future allele frequencies may drift.

Since the peacock population is isolated, its alleles would shift away from Hardy-Weinberg equilibrium.

The peacocks are sexually selective when choosing mates, so future allele frequencies may drift.

Explanation:

Opsins are proteins that are found in the light-sensing cells in the human eye. Different opsin proteins are sensitive to different colors of light. The instructions for creating the type of opsin sensitive to red light are found on a gene known as OPN1LW, which is on the X chromosome. A genetic mutation in the OPN1LW gene can lead to a form of color blindness that affects a person's ability to detect red light. However, women have two copies of the X chromosome, and they have normal color vision if only one copy contains the mutation. Why do women who carry one copy of the mutated gene still have normal color vision?

Answers

Answer:

Women who carry one copy of the mutated gene still have normal color vision because they have another copy, which is not mutated, in the other X chromosome that will be the dominant one. As a result, the women are carriers of the mutated gene but not color blind.

Explanation:

Colorblindness is a sex-linked mutation. A woman has two X chromosomes, while a man has one X chromosome and one Y chromosome. The mutated gene that causes color blindness is on the X chromosome, and it is OPN1LW. So if a woman has one mutated OPN1LW in one of her two X chromosomes, the OPN1LW gene in the other X chromosome will be the dominant one stopping the woman from being colorblind.

In the case of men, as they only have one X chromosome, if there is a mutation on the OPN1LW in the X chromosome, the men will be colorblind because there is no extra copy of the gene, as it is in women.
