Which of the following correctly states how genes, chromosomes and traits are related? A Chromosomes are part of genes. The traits determine our chromosomes. B Traits are segments of chromosomes. The chromosomes make up our genes. C Genes are segments of DNA on chromosomes. The genes code for proteins that make our traits. D Chromosome are make up of DNA which is divided into genes. The traits are all of the chromosomes we find in a cell.
Answer:
C
Explanation:
While D could be the right answer if it was phrased better the most liekly answer seems to be C as Genes are small segments of DNA and DNA makes up chromosomes in turn causing chromosomes to be made up of genes. I believe that proteins do make our traits so C is the best answer.
Genes are segments of DNA on chromosomes. The genes code for proteins that make our traits. So, the correct option is (C).
What are Genes?Genes are defined as the basic units of heredity passed from parent to child that are made up of sequences of DNA and arranged one after the other at specific locations on chromosomes in the nucleus of cells.
Genes are found in each one of the 37 trillion cells that make up the body. Every cell has a nucleus and inside each nucleus are chromosomes and all chromosomes are made of DNA, molecules that contain genetic information called genes.
A chromosome contains hundreds to thousands of genes where each normal human cell has 23 pairs of chromosomes, for a total of 46 chromosomes. Trait is any gene-determined characteristic and is often determined by more than one gene.
Thus, Genes are segments of DNA on chromosomes. The genes code for proteins that make our traits. So, the correct option is (C).

Leaves of a healthy potted plant were coated with Vaseline to block stomata. Will this plant remain healthy for long? State three reasons for your answer.
➜ If waxy coating is made on the surface of leaf, loss of water in the form of water vapour does not take place. Even the gaseous exchange will not take place. So, photosynthesis will either be reduced or will not take place.
The plant will not remain healthy for long because:
[i] Exchange of gases will not take place.
[ii] Photosynthesis will either be reduced or will not take place due to lack of CO2.
[iii] Transpiration will not take place, so there will be no mechanism of cooling in hot weather.
We have 13 different clotting factor proteins in our blood. Do you think hemophilia is controlled by one or multiple genes?
Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern . The genes associated with these conditions are located on the X chromosome, which is one of the two sex chromosomes . In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. Basically it's whatever you believe it is.

Caenorhabditis elegans is a species of soil-dwelling nematode (roundworm) that feeds on soil bacteria, including Bacillus thuringiensis.
a. True
b. False
Answer:
b. False
Explanation:
Caenorhabditis elegans is a well-known species which is widely used in genetic experiments (i.e., it is a model organism). C. elegans is a soil nematode that eats bacteria, but its survival depends on the ability to distinguish toxic from non-toxic ones. C. elegans cannot feed Bacillus thuringiensis because this bacterium produces a toxin Bt protein that damages its gut, thereby producing the death of this nematode. Interestingly, it has been proposed that Bt toxin pathways might be exploited for the design of new generation nematicides.

how does the ribosome read the mRNA?
Answer:
A ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain).

BRAINLIEST: In dolphins, to have spots on the skin is a recessive trait. One spotted dolphin and one solid gray dolphin have a baby spotted dolphin. Go through the following steps to figure out the genotype of the parent dolphins.
1) what are the POSSIBLE genotypes of the solid grey dolphin?
2) what is the genotype of the baby spotted dolphin?
Answer:
1) Ss
2) ss
Explanation:
Spots (recessive) - s
No spots (dominant) - S
So the possible combination to get a baby spotted dolphin may be: Ss and ss
Punnett Square:
| S | s |
s | Ss | ss |
s | Ss | ss |
So the genotype of the Solid gray dolphin might have been a dominant allele and a recessive allele, which is Ss.
Moreover the genotype of the spotted baby dolphin might me ss.

Which factors affect the gravitational force between two objects?
Answer: The size of each object and the space between them.
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

Which of the following is not a abiotic factor ?
A. Dirt
B. Sunlight
C. Water
D. Air
Answer:
A) Dirt
Explanation:
Our environment comprises of two factors namely biotic factors and abiotic factors. Biotic factors are those in an ecosystem that consists of all living organisms such as plants, trees, humans, insects, animals, birds, etc. These living organisms will interact with each other and sustain their life.
Abiotic factors are those that contain non-living organisms. These factors include soil, air, water, sunlight, etc. These factors often have a greater impact on biotic factors. From the question, a plant is a living thing and it belongs to the biotic factor.
Answer: They are all Abiotic factors actually but my best guess would be B. sunlight

Why do large islands usually have more species than smaller islands?
Answer: Reason Why
Explanation: A bigger target is easier to hit than a small one, and a big island is more likely to have species land on it by chance than a small one is. Larger islands have more space than smaller islands, so there are likely to be more resources available for species to use. The opposite is true for smaller islands.
What is biomass burned to produce
Answer:
Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas. However, the plants that are the source of biomass for energy capture almost the same amount of CO2 through photosynthesis while growing as is released when biomass is burned, which can make biomass a carbon-neutral energy source.

The University of Illinois has been conducting one of the longest selection experiments, begun in 1896 by C.G. Hopkins. Researchers have been selecting for high corn oil content (as measured in % dry mass). Researchers select those plants with the highest corn oil content, and use only those individuals to seed the next generation. Here is a portion of actual data from their experiment:
1899 mean oil content in entire population: 5.65% dry mass
mean oil content of selected plants: 6.30% dry mass
1900 mean of oil content in entire population: 6.10% dry mass
Calculate the heritability of corn oil content (% dry mass). For full credit, show your work, including any equations used.
Answer:
0.725
Explanation:
This type of question is a concept of Narrow-sense Heritability and Artificial selection used by plant breeds.
So, heritability = R/S
where;
R = response to selection
S = selection differential
S further implies the difference in mean oil content between base population & selected population.
S = 5.65 - 6.30 = 0.65% ( where the negative sign are not regarded)
R implies the difference in mean oil content between the offspring or population after implementation of selection and the base population.
R = 6.10 - 5.65 = 0.45%
∴
Heritability = R/S = 0.45% / 0.6%
= 0.725
Thus; the heritability in the oil content of corn in the given set of population = 0.725.
