Describe the different ways that substances are moved across a cell membrane.

Biology
1 answer:
RUDIKE [14]4 years ago
7 0

Answer:

Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). The passive forms of transport, diffusion and osmosis, move materials of small molecular weight across membranes.

Mendel referred to what we know of as alleles as ""factors."" What did he conclude happens to these factors during gamete format
Anettt [7]

Answer:

option A. the factors separate

Explanation:

The Mendel referred alleles as factors. Mendel was unaware about gene but he knew that there are two factors for a single character. The single factor gets transferred from each parent. The gene contains two alleles/factors. The alleles/factors from both mother and father separates at the time of formation of gametes. These gametes from both parents containing alleles/factors recombines and thus forming a zygote.

Thus, factors separate during gamete formation. So, option A is correct.

Can you label these chromosomes with the correct genetic terms pearson
julia-pushkina [17]
I found the exercise on the internet. Attached is an image with the terms and the representation of the chromosomes mentioned above.

The term for the position a) would be homologous chromosomes. Position b) is gene locus. Position c) is recessive allele because it is represented by a small letter. Position d) is centromere. Position e) is sister chromatids. Position f) is alleles. Position g) is dominant allele because it is represented by a capital letter.

Why do you think studying heredity is important?
DanielleElmas [232]

Answer:

1) The study of heredity is important to determine which traits or characteristics will be passed on from parent to children. It helps us to determine the probability or chance of a disease to occur in children.

2) Yes, we can predict the genotype outcome of an offspring if we have an idea about the genome of the parents. We determine the genotype of the parents and can known about the genotype of the children by constructing a punnet square.

3) The genotype and phenotype are alike by the fact that the genotype will be responsible for developing a particular phenotype. They are different because genotype reflects the genetic makeup of the person. Phenotype reflects the physical characteristics or traits of a person.
