Answer:
Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.
Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.
Explanation:
Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave. - this is true. Prior to cell division, DNA molecules are organized into large structures called chromosomes. Specific regions of a DNA molecule are called genes. These dictate specific proteins which control our traits.
Genes contain thousands of chromosomes that carry specific information about building proteins for a particular trait. - this is false - genes are segments of DNA that control specific traits by dictating the structure and functions of proteins. Chromosomes contain thousands of genes
Chromosomes are small sections of DNA that contain specific information about a trait to build proteins that people inherit. The thousands of different chromosomes passed from the parents allow for humans to look uniquely different.
- this is false - chromosomes are large structures, genes are the relatively small sections of DNA. Humans have 23 pairs of chromosomes, not thousands.
Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring. - this is true. In diploid organisms, like humans, have two copies of each chromosome. These chromosomes contain slightly different versions of genes, which make us unique.
Answer:
Sun > Grass > Deer > Lion
Explanation:
The sun begins a food chain because its light is needed for a plant, in this case grass, to grow.
An animal that eats grass is the deer, who is a primary consumer.
An animal that eats deer is the lion, who is a tertiary consumer in this case.
The lion has no natural predator, and thus is at the top of this food chain.
This ecosystem can be one found where grass, deer and lions exist, for example, the deciduous forest in the eastern United States.
Answer:C
Explanation:
The arteries are not a cell bc that is too simple a tissue is also too simple its not a system bc arteries are not a lot of organs working together so its C
Answer: It must be based on scientific observations that can be repeated in a controlled setting.
Explanation:
A scientific claim is the claim which includes statement(s) which is verified by the observations obtain after multiple experimental trials or procedures in a controlled experiment. A scientific claim can only be considered as wrong when a valid argument or prove satisfies the fact why it is wrong.
