Curly hair (C) is dominant where straight hair (c) is recessive. If a person who is CC were to have children with a person who is cc, could it be possible for them to have a child with straight hair?
a
yes
b
no
Answer:
No, it would not be possible to have a child with straight hair.
Explanation:
The Punnett cross would be CC x cc, so all the offspring would be Cc. Since straight hair is only cc, the kids would not have straight hair.
Awnser:
yes, it is possible :)
Explanation:
Their children would would have the dominant trait, curly hair, and the recessive straight hair gene hidden in their dna. If there was a chance that one of their curly haired children met with a cc-partner with straight hair, then they would have a 1 in 2 chance. Even with a Cc-partner, there would be a 1 in 4 chance of the straight hair trait "skipping a generation".

Explanation:
If the DNA molecule is only composed of four possible nitrogen bases, how can thousands of different proteins be formed from such a limited set of fixed shapes?
Answer:
nucleotides are only building blocks whose combinations determine different codons which subsequently associate in a sequential manner in order to create different amino acid combinations
Explanation:
A gene is a specific segment of DNA whose (nucleotide) sequence is copied into an RNA during the process of transcription, typically a messenger RNA (mRNA) molecule which is subsequently used to synthesize a protein. During translation, each triplet of nucleotides, i.e., each codon, corresponds to a specific amino acid. There are 64 possible codons (4³: 64), which can combine in different ways to create different amino acid combinations, and thus they are responsible for the generation of a huge amount of proteins coded by a given genome.

Think about the meaning of these words fruit seed germinate cotyledons, embryo ,plumule ,dormancy,root hairs. Write a sentence containing each of these words
Answer:
When a seed, taken from a fruit, is planted and watered under the correct temperature, it breaks dormancy, and the embryo germinates; first, the root grows covered by root hairs, then the cotyledons appear, and finally, the plumule elongates to reach the light.
Explanation:
Fruit: It forms by the mature ovary of the flowers. This structure contains and protects the seeds in its interior. Its principal function is to transport seeds to a distant area away from the parental plant and let the new plant emerge under the correct environmental conditions. The fruit develops different strategies to accomplish its function. Seed: Refers to the fecundated and mature ovule. This structure is the typical dissemination and dispersion unit of spermatophyte plants. Seeds are formed of three tissues. An embryo. A seminal tegument that covers and encloses the latent embryo. And the endosperm -a nutritious tissue-. Seeds develop and grow under the protection of the fruit body. Embryo: It is formed after fecundation. It composes of growing cotyledons, an epicotyl, and a hypocotyl. The tegument and endosperm of the seed protect the embryo from dehydration and denutrition. Once the seed is in the correct place, the embryo grows and emerges. Cotyledon: The two first leaves of the embryo. They have reserve nutritive tissues to help the embryo grow. It also performs photosynthesis. The embryo usually develops one or two cotyledons and one radicule or root hair. Plumule: First shoot of the young emerging plant. When the embryo is growing, it elongates to reach more sunlight. Root hairs: Extention of the roots´ cells that look like hairs and whose principal function is to absorb nutrients and water from the ground. They can be found in the maturation area of the root. Germination: Process of development and the emergence of the embryo. These are a series of steps that must occur in the seed from the moment the embryo begins to develop until a newly emerged plantule is formed. For germination to occur, there must be the appropriate environmental conditions. Dormancy: Period in which an alive seed can not germinate because there is a condition inside the seed that does not allow germination to occur yet. The seed is in dormancy, but it keeps viability.

Do mutations in body cells contribute to genetic variation?(1 point)
A) No, the causes of body cell mutations are outside the body and cannot alter DNA.
B) Yes, the mutations can be passed on to offspring and contribute to variation in the population.
C) Yes, these body cell mutations lead to mutations in the gametes.
D) No, the mutations cannot be passed to offspring and only affect the individual.
A mutation is the alteration of the genetic sequence of an organism, which can either be inherited or cannot be inherited. The mutation when transmitted to the offspring leads to genetic variation.
The correct answer is:
Option B. Yes, the mutations can be passed on to offspring and contribute to variation in the population.
Mutation is the change in the genetic sequence of the organism, which can be caused due to environmental factors and can be inherited.
The mutations can lead to genetic disorders, chromosomal disorders, or any other conditions. The mutations like a disease or adaptation that can be passed onto the offspring can result in genetic variation.
The mutation leads to genetic diversity, as the mutation is also the first step towards evolution. The organisms better suited to the environment will survive more and adapt more. These changes in the organisms will be inherited by the offspring leading to genetic variation.
Therefore Option B is correct.

Cellular differentiation progressively restricts cell fate because the unexpressed genes in the cell:Select all that apply become more densely packed with nucleosomes accumulate both point mutations and deletions accumulate point mutations undergo irreversible repression accumulate deletions.
Answer:
undergo irreversible repression
Explanation:
Cellular differentiation refers to the process by which one cell and/or cell population divides and differentiates into more specialized cells. During cell fate differentiation, epigenetic marks modify chromatin structure in order to hamper the accessibility of the transcriptional machinery and transcriptional factors to different genes, which are irreversibly repressed. These epigenetic marks include DNA methylation and histone modifications (e.g., histone acetylation, histone methylation, etc). For example, it has been shown that DNA methylation and histone H3 lysine 27 tri‐methylation (H3K27me3) are epigenetic repressive marks on genomic regions that play a major role in gene expression programs during cell fate differentiation.

Which mutation is harmful to the organism?
Answer:Insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions and deletions are usually more harmful than a substitution in which only a single amino acid is altered.

Is enzyme substrate complex concentration the product of enzyme concentration and substrate concentration?
Answer:
Yes
Explanation:
The enzyme substrate complex may be defined as the enzyme when interacting with the substrate at an active site and it produces a new product in the process. It is temporary molecule formed when the substrate comes in contact with the enzyme.
An enzyme is the molecule of a protein which acts like an organic catalyst and a substrate is a the molecule which interacts with the specific enzyme to form a product.
Therefore, the enzyme substrate complex concentration is the product of the substrate concentration as well as the enzyme concentration.
