Describe the four types of
chromosomal mutations.
Answer:
1. Deletion is where a section of a chromosome is removed.
2. Translocation is where a section of a chromosome is added to another chromosome that is not its homologous partner.
3. Inversion is where a section of a chromosome is reversed.
4. Duplication occurs when a section of a chromosome is added from its homologous partner.

Tay Sachs is a recessive disease (t) that causes an inability to process certain nutrients which then build up in the brain, resulting in death (at a very young age). A man and a woman had a child born with this disease, but neither have the disease (otherwise they would have died as young children!). What must their genotype be in order for them to have a child with the disease? Explain your reasoning.
Answer:
Tt (both heterozygous)
Explanation:
According to this question, Tay Sachs is a recessive disease (t) that causes an inability to process certain nutrients which then build up in the brain, resulting in death (at a very young age). This means that this disease can only be phenotypically expressed when the recessive alleles are both present in the gene i.e. tt.
If a man and a woman had a child born with this disease, but neither have the disease, it means that both of the parents are dominant but heterozygous (carriers) for the disease. This means that they both have a genotype "Tt". So when they both mate i.e. Tt × Tt, they produce the following offsprings: TT, Tt, Tt, and tt.
The "tt" offspring is the child with the Tay Sachs disease.

List three ways that Earth’s systems interact, and briefly describe those interactions.
volcanoes because they are built from the earth
Explanation:
What part of DNA determines traits?
Answer:
The traits of a living thing depend on the complex mixture of interacting components inside it. Proteins do much of the chemical work inside cells, so they largely determine what those traits are. But those proteins owe their existence to the DNA (deoxyribonucleic acid), so that is where we must look for the answer.

When an egg and sperm form an embryo, the offspring that is formed will have genetic traits that are
A. Inherited from only one parent.
B. Created by the environment.
C. Passes in from two parents.
D. Learned from sibling
Answer:
C.
Explanation:
In reproduction, the offspring will will have genetic traits from both the mother and father--as half of out mother's DNA + half of our father's DNA = our full set of DNA.
The offspring have genetic traits that are Passes in from two parents.
When the two haploid gametes fuse they form a diploid embryo that have the characters from both the parents.Explain genetic traits?A genetic trait is a specific characteristics of an individual that are determines by the genes, environmental factors or by the combination of both. Traits can be :-

The K-selection reproductive strategy maximizes the survival of offspring
by producing
Ofew offspring with high levels of parental care
Ofew offspring with low levels of parental care
O many offspring with high levels of parental care
Omany offspring with low levels of parental care
Answer:
The K-selection reproductive strategy maximizes the survival of offspring by producing few offspring with high levels of parental care.
Explanation:
Depending on how many offsprings members of a species produce and how much care they invest in them, we can divide species into two categories:
r-organisms. These organisms produce many offspring, sometimes even thousands of them. They live in unpredictable, dangerous environments with a lot of predators. This is why most of their young die. It's important for at least some of them to survive so that they can continue reproducing and keep the species alive. The parents don't invest much care into their young. Some examples of these species are mice, rabbits, weeds, and bacteria.K-organisms. These organisms are the opposite of r-organisms. They live in more stable environments, which guarantees that their lifespan will be longer. This is why it's not necessary for them to produce many offspring. Parents invest a lot more care into their young. Some examples of these species are humans, elephants, horses, and primates.Based on this information, we can conclude that the K-selection reproductive strategy maximizes the survival of offspring by producing few offspring with high levels of parental care.
Answer:
Answer choice A
Explanation:
Few offspring with high levels of parental care is a characteristics of K-selected species.
care of chicks at the age of between 8 to 20 weeks is called ????????
Answer: Brooding
Explanation:
Chicks are kept at high temperature after hatching this process is called brooding.
The chicks require 95-100 degrees temperature for brooding they are not allowed to mix with the flocks until 20 weeks after their birth.
Until this time the chicks learn to eat and drink water.
Overheated chicks can dehydrate and they grow slowly.
Is loss of predator a density-dependent or density-independent factor?
Answer:
density-dependent
Explanation:
limiting factors cause a population's per capita growth rate to change—typically, to drop—with increasing population density. one example is competition for limited food among members of a population. whereas, density-independent factors affect per capita growth rate independent of population density. examples include natural disasters like forest fires.

Explanation:
This DNA strand consists of eight pairs of nitrogenous bases. How many different sequences of eight bases can you make? Explain how you found your answer.
Answer:
Explanation:
it would be 4 (possible bases) to the power of 8 because you need to multiply 4, eight times for the number of sequences. Therefore, the answer is 65, 536 possible sequences.
3. Which statement correctly defines digestion?
Digestion is a reversible process due to mechanical digestion.
Digestion is the process of breaking down food into smaller molecules.
Digestion is mixing food with saliva, which is when mechanical digestion starts.
Digestion is the process of chewing food, which is referred to as chemical digestion.
Answer:
B) Digestion is the process of breaking down food into smaller molecules.
Explanation:
Answer:
Your answer is B
Explanation:
What are some benefits of enzyme production in the process of digestion.
Answer:
definition;
enzymes are protein that catalyze speed up the biochemical reactions and are not changed during the reaction . the molecules at which enzyme work are called substrate and enzymes convert them into different molecules called products.
benefits of enzyme in digestion ;
enzyme lower the activation energy in several ways. they may alter the shape of substrate and reduce the requirement of activation energy . enzyme may also lower activation energy by bringing substrate in correct orientation to react . enzyme break down carbohydrates, lipids and proteins which are component of human food .In digestion larger molecules are broken into smaller molecules like amino acids ,simple sugars ,fatty acid ,vitamins ,salts and water to provide to cells. these molecules are a part of larger molecules like protein ,polysaccharids and lipids . enzymes like amylaze, lypase ,salivary amylase, pepsin ; it is a very strong protein digesting enzyme it is released in its inactive form pepsinogen which is converted into pepsin with the help of H-C-L hydrochloric acid it takes part in digestion in stomach

why should damage be repaired before a cell enters mitosis
Answer:
Cells do not repair damage to DNA during mitosis because telomeres could fuse together. ... Throughout a cell's life, corrective mechanisms act to repair DNA strand breaks. The exception is during the critical moment of cell division, when chromosomes are most vulnerable.
