Describe the major differences between the ecological niches of humans and cockroaches. Are these two species in competition? If so, how do they manage to
coexist?
Answers
Humans: large omnivorous animals, apex predator in many ecosystems
Cockroaches: small detrivores.
Humans: Sleep at night.
Cockroaches: Spend daytime hidden away, preferably in dark crevices.
Humans: Extensively modify the environment.
Cockroaches: Some species can burrow.
Are these two species in competition?
No. Our diets overlap a bit (e.g. stored grains), but we exploit food sources that cockroaches can't, and vice versa. We do not compete for homesites or mates at all.
The major differences between the ecological niches of humans and cockroaches depend on the functional role they play, the space they live, and the group (trophic level) they belong.
What is an Ecological niche?An ecological niche can be regarded as an area or set of environmental factors or the surroundings of an individual where they perform their functional role.
Humans being omnivores have a generalized niche where they particularly have many options to play a functional role (feeding habit).
Cockroaches play the role of decomposers which is also an important part of any ecosystem. Living organisms are interdependent, so they need each other in order to survive. Therefore, it is wrong to say that humans and cockroaches are in competition. Cockroaches unlike humans live in really dirty and dark places because in such conditions they easily find food. While humans take a rest in dark (night) and search for their food in the daytime.
Humans take fresh and cooked food, while cockroaches shred dead and decaying organic matter into smaller pieces so that it would be eaten by recycling bacteria.
Therefore, these two different species are not in direct competition and survive without affecting each other's ecological niche.

Considering a group of fruit flies.
The trait of interest is the color of the body of the fruit flies.
There are two observable phenotypes:
- Gray body.
- Black body.
This trait is coded by two alleles:
- B codes for the "gray body"
- b codes for the "black body"
A certain fruit fly shows the phenotype "black body" and its genotype is "bb"
→ both alleles of the genotype of the fruit fly are equal, which means that this individual is homozygous for the given trait.

Heart cells have different characteristics than skin cells because heart cells express different genes than skin cells.
Humans as multicellular organisms possess different cells in our body system. These cells perform varying functions in the body. The different functions performed by different cells is attributed to the cellular differentiation. Cellular differentiation is the process whereby an undifferentiated cell becomes specialized. The cellular differentiation occurs due to the difference in gene expression in each specific cell. All cells contain the same DNA sequence, however, they are expressed differently.

3. Which organs are responsible for
protecting the body? How?
Answers
Answer:
Primary lymphoid organs: These organs include the bone marrow and the thymus. They create special immune system cells called lymphocytes. Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils and certain tissue in various mucous membrane layers in the body (for instance in the bowel)
Explanation:
hope this helps
The thymus is located behind the breastbone above the heart. This gland-like organ reaches full maturity only in children, and is then slowly transformed to fatty tissue. Special types of immune system cells called thymus cell lymphocytes (T cells) mature in the thymus. Among other tasks, these cells coordinate the processes of the innate and adaptive immune systems. T cells move through the body and constantly monitor the surfaces of all cells for changes.
Lymph nodes are small bean-shaped tissues found along the lymphatic vessels. The lymph nodes act as filters. Various immune system cells trap germs in the lymph nodes and activate the creation of special antibodies in the blood. Swollen or painful lymph nodes are a sign that the immune system is active, for example to fight an infection.
The bowel plays a central role in defending the body against germs: More than half of all the body's cells that produce antibodies are found in the bowel wall, especially in the last part of the small bowel and in the appendix. These cells detect foreign substances, and then mark and destroy them. They also save information about the substances in order to be able to react more quickly the next time. The large bowel also contains harmless bacteria called gastrointestinal or gut flora. Healthy gut flora make it difficult for germs to spread and enter the body.
Mucous membranes support the immune system in other parts of the body, too, such as the respiratory and urinary tracts, and the lining of the vagina. The immune system cells are directly beneath the mucous membranes, where they prevent bacteria and viruses from attaching.
The tonsils are also part of the immune system. Because of their location at the throat and palate, they can stop germs entering the body through the mouth or the nose. The tonsils also contain a lot of white blood cells, which are responsible for killing germs. There are different types of tonsils: palatine tonsils, adenoids and the lingual tonsil. All of these tonsillar structures together are sometimes called Waldeyer's ring since they form a ring around the opening to the throat from the mouth and nose.
There is also lymphatic tissue on the side of the throat, which can perform the functions of the palatine tonsils if they are removed.
The spleen is located in the left upper abdomen, beneath the diaphragm, and is responsible for different kinds of jobs:
It stores various immune system cells. When needed, they move through the blood to other organs. Scavenger cells (phagocytes) in the spleen act as a filter for germs that get into the bloodstream.
It breaks down red blood cells (erythrocytes).
It stores and breaks down platelets (thrombocytes), which are responsible for the clotting of blood, among other things.
There is always a lot of blood flowing through the spleen tissue. At the same time this tissue is very soft. In the event of severe injury, for example in an accident, the spleen may rupture easily. Surgery is then usually necessary because otherwise there is a danger of bleeding to death. If the spleen needs to be removed completely, other immune system organs can carry out its roles.
How is the nitrogen cycle important to humans?
A.It produces free nitrogen that humans can breathe.
B.It converts nitrogen into a form that humans can obtain by eating other organisms.
C. It produces nitrogen compounds that humans can breathe.
D. It converts nitrogen into a form that humans can obtain by absorbing it through their skin.
Answers
The nitrogen cycle is important to humans in the following way: it converts nitrogen into a form that humans can obtain by eating other organisms (option B).
What is the nitrogen cycle?Nitrogen cycle is the natural circulation of nitrogen in a series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
During the nitrogen cycle, atmospheric nitrogen is converted to nitrogen oxides by lightning and deposited in the soil by rain, where it is assimilated by plants and either eaten by animals (and returned as faeces) or decomposed back to elemental nitrogen by bacteria.
The usable form of nitrogen that is assimilated by plants becomes accessible to humans when they consume the plants, hence, depicting the importance of the nitrogen cycle.

Show the reciprocal cross: A red-eyed female (homozygous) and a white-eyed male. How many offspring will have white eyes and what is their sex?
Answers
When we see the reciprocal cross between a red-eyed female (homozygous) and a white-eyed male,we observe that none of the offspring will have white eyes. Additionally, the sex of the offspring will be half male and half female since the ratio of males to females is 1:1.
The reciprocal cross for a red-eyed female (homozygous) and a white-eyed male can be shown as follows:Female (XrXr) x Male (XwY). Females have two X chromosomes and males have an X and a Y chromosome. Red eyes are dominant to white eyes; therefore, we use Xr to represent red eyes and Xw to represent white eyes.
The offspring are as follows:All F1 females are heterozygous (XrXw).All F1 males are hemizygous (XrY).The F1 generation will have red eyes since the dominant allele is present.
None of the F1 individuals will have white eyes as the recessive allele is not present in the F1 generation.
