Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell. They contain all the genetic information of an organism. Humans have 46 pairs of chromosomes, with half from each parent. Which of the following best describes why the offspring will receive only half of the parents' chromosomes?
A)Chromosomes assort independently, and crossing-over occurs.
B)Gametes contain homologous pairs from the mother and father.
C)Diploid eukaryotic cells become haploid before fertilization.
D)The cell cycle stops, allowing for extra haploid cells to be made.
Answer:
C
Explanation:
I am pretty sure answer is C.
Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell, and they contain all the genetic information of an organism because chromosomes assort independently and crossing-over occurs, as in option A.
What is the function of the chromosome in meiosis?The chromosomes present in the parent cell duplicate in the S phase of the cell cycle, and in the meiosis phase of the cell cycle, the daughter chromatids segregate and form four haploid cells from the parent cell. The child or offspring is the result of the fertilization of the sperm and the ovum, and the zygote is formed from the process that develops into the offspring, and the zygote has half the genetic contents of the paternal and maternal parents. In this way the chromosomes separate in the meiosis.
Hence, Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell, and they contain all the genetic information of an organism because chromosomes assort independently and crossing-over occurs, as in option A.

Autotrophic means making your own food, providing it without consuming other organisms. Heterotrophic is the opposite: think of the prefixes auto- meaning self and hetero- meaning different.
Most plants use photosynthesis to get energy from the sun; that's their own source, no eating other organisms necessary. Examples are grasses, flowers, trees.. most mainstream plants. There are a few exceptions, like something nasty like a Venus flytrap.

1. One of the central themes in biology is how DNA, RNA, and proteins are related. Describe how genetic
information is passed among those types of molecules. Include the results of the processes of
transcription and translation
Answer:
Transcription uses a strand of DNA as a template to build a molecule called RNA. The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein building machines.

The scientific name of an organism is made up of what two group names?
Answer:
Genus species
Explanation:
Scientists use a special naming system for organisms. It is made up of two words.
The first word is the genus of the organism and the second word is the species of the organism.
The first word, which is the genus, is always capitalized, but the second is not. Both words are italicized if possible, but if you are handwriting the scientific names, an underline suffices.

Suri designed an experiment to plant lima bean seeds. Her variable was to change what kind of light each plant received. She used
a different kind of light with each plant. She hypothesized that the plant grown under the natural sunlight would have the greatest
amount of growth. What can she conclude after the results of her experiment?
A) photosynthesis does not require any light for a plant
B) plants grow best when they are grown under a black light
C) photosynthesis can happen under lights that are not the sun
D) plants cannot grow unless they are exposed to natural sunlight
Answer:
Option C
Explanation:
Light from the sun (sunlight) is the most suitable form of light energy that necessary for plant growth and blooming, but artificial light can also be useful in helping plants grow. For example, low-light foliage plants such as the peace lily can grow quite readily in offices that do not have windows with just about enough artificial light.
Answer:
The correct answer is C: "photosynthesis can happen under lights that are not the sun"
Explanation:
A) photosynthesis does not require any light for a plant. This is not correct, as in order to photosynthesize any plant need light. In its absence, the plant does not obtain any energy and is not able to produce organic matter.
B) plants grow best when they are grown under a black light: This is not correct because, in comparison with other lights of different colors, plants grown under a black light are ones that show the less growth rate.
C) photosynthesis can happen under lights that are not the sun: This is correct. Photosynthesis can indeed occur under other lights. There are different factors to take into count if we want plants to grow under artificial conditions, such as the amount of light, times of light per day and the color of the light.
D) plants cannot grow unless they are exposed to natural sunlight: This is not correct. Although sunlight is the best option for any plant to grow in the correct time and form, these organisms might also grow under artificial lights of different colors or wavelengths. The plant might respond in different ways, depending on the light it is exposed to, but eventually, it will show some growth.

Carbon-dioxide gas is essential for maintaining life on earth.
Carbon-dioxide present in the atmosphere comes from breathing of animals and volcanic eruption. this carbon-dioxide absorb by the plants (biosphere) in the process of photosynthesis. This carbon-dioxide is incorporated in the soil (geosphere) with the dead bodies of plants and animals and decomposition of these bodies occurs and carbon-dioxide gas again releases in the atmosphere. Carbon-dioxide gas is also dissolved in the water bodies where it is required by the plants for photosynthesis and made food for the marine animals.
