Explanation:
The common housefly can transmit the pathogens that cause shigellosis, typhoid fever, E. coli, and cholera. The disease-causing agents can either be transmitted by the body hairs or by the tarsi which are transmitted to food or surfaces when the fly lands.

One recent approach to vaccine development has been production of peptide vaccines. In these vaccines, antigenic peptides are injected instead of whole bacteria or viruses. Peptide vaccines have not been particularly useful against viral pathogens because viral infections require a CD8+ T cell mediated immune response. Why is a peptide vaccine unable to create such a response?
Answer:
Explanation below
Explanation:
Immunization is the process of protecting the body from infections. This can be divided into two, namely
1. Natural immunization
2. Artificial immunization
Natural immunization is the one that is being developed by the body naturally, to protect the body from infections. This is usually known as the white blood cells.
Artificial immunization is being developed through the introduction of atenuated organisms into the body, so that the body can react by producing antibodies against that infectious organisms. This is known as vaccination.
The peptide vaccines have been developed for the body to be able to produce antibodies against some infections.
It should be noted that, owing to the relatively small size of peptides, they are often weakly immunogenic by themselves and therefore require carrier molecules, to add chemical stability and adjuevating for the induction of a robust immune response.

Which best describes the ovary?
it produces progesterone.
it is the organ in which a fertilized egg grows.
it produces testosterone.
it is the location for egg fertilization.
The option that best describes an ovary is that is produces progesterone.
Functions of ovaryThe ovary is part of the female reproductive system and they are two oval-shaped organs that lie to the upper right and left of the uterus.
The three main functions of the ovary are
they secrete hormones, they protect the eggs a female is born with and they release eggs for possible fertilization.The hormones secreted by the ovary are the female hormones oestrogen and progesterone.
Progesterone functions mainly to regulate the condition of the inner lining (endometrium) of the uterus.
Therefore, the option that best describes an ovary is that is produces progesterone.

Which of the following is a product of photosynthesis?
a. carbon dioxide
b. sugar
c. sunlight
d. water
Answer:
B. Sugar
Explanation:
Sugar, or glucose, is the main product of photosynthesis. It is the reason why photosynthesis occurs, as plants use glucose as food or a source of energy. Sunlight, water, and CO2 are all components of making glucose, not products. Another product of photosynthesis is oxygen, which we then use in turn for cellular respiration.
Answer:
I don't see it on there but I think you're missing an option
Explanation:
-The answer to this is oxygen
(glucose sugar could also be correct depending on what your question looks like)

an explanation of a natural phenomenon supported by many observations and experiments over time
Answer:
Explanation of a natural phenomenon, supported by many observations and experiments over time, corresponds to a scientific theory.
Explanation:
A scientific theory begins with the observation of a natural phenomenon and the formulation of a hypothesis that explains its existence, which must be proven through observation and experimentation.
The approach of a theory follows the scientific laws and must be established on the basis of rigorous experimentation and measurement, establishing a relationship between what is observed and what can be proven, in such a way that a theoretical principle is elaborated to provide an explanation of the phenomenon.
A theory is subject to the scrutiny of the scientific community and can be refuted, when other data or experiments appear to oppose it. When the argument of a theory cannot be refuted, and is universally accepted, it becomes a scientific law.

You have learned about how to sample a population and estimate size from density. In this
activity, you will: construct a model of a population, sample the population to determine its
density, then use its density to determine its size.
Part One: Construct the Model
Materials
1 piece of 8.5 by 11 in. letter paper
1 pen or pencil
1 ruler
50 small dry beans or other small objects such as buttons
1 small cup
Directions:
1) Use your pen or pencil and ruler to divide the paper into four equal sections.
2) Place the 50 beans into a small cup.
3) Scatter the beans as evenly as possible over the entire paper, making sure to get some of
the beans into each section.
Student Name:
Modeling Population Size
Part Two: Use the Model to Estimate the Size of the Population
In your model, each bean represents a starfish and the paper represents its ocean floor habitat.
1) Within the habitat, choose one of the four sections and count the number of starfish in that
section.
2) Use your ruler to measure the dimensions of the section you chose and calculate the area
that you sampled.
3) Calculate population density based on your sample.
4) Use your ruler to measure the dimensions of the entire habitat and calculate the total
habitat area.
5) Use your calculated population density and total area to estimate total population size.
6) Compare this estimation to your known population size (50). Did you under‐ or
overestimate based on your sample?

Why would the shrimp in the ecosphere die if there was no sunlight?
Answer:
The shrimp would die wthout sunlight because they eat algae and algae live on the water's surface. Algae undergo photosynthesis and for photosynthesis to occur, sunlight is necessary. If there is no sunlight, there is no algae. And without the algae around the shrimp no longer have anything to eat. Therefore, without the sunlight (and algae) the shrimp will not be able to survive.

Imagine that you are a genetic counselor working with the first daughter in the last generation of the pedigree shown. She is married to a man with no history of ald in his family. The couple plans to have children and they want to know the chance of their first child having ald. How will you advise them?.
The chance of your first child having ald is 25%.Becose the adl gene may be recessive in this family.
How to advise them on family genetics?Recessive genes produce proteins considered “defective” as they become inactive. That is, they are hidden (recessive) with the presence of a dominant gene manifesting their characteristics in the absence of their dominant allele. The adl gene may be recessive in this family.
With this information, we can conclude that the chance of your first child having ald is 25%.
