Answer:
they considered valid but a certain idea of acquired characteristics being inherited was rejected
Explanation:
his theory was that if the environment demanded a need or use of a structure in an organism it developed it in response to demand leading to natural use or disuse of structures which he said that these new structures would be passed to their offspring leading to emergence of a new species. scientists accepted that the environment has a role in directing phenotypic changes in an individual taking a body builder for example since his muscles will become huge due to continuous use of the muscles in exercises
but scientists rejected his theory of these acquired characteristics were inherited since phenotypically acquired characteristics that do not affect the genotype of an individual can't be inherited
Endometriosis occurs when endometrial tissue, which normally grows inside the uterus, grows outside the uterus. Based on the model, what effects would you expect these growths to have on the female reproductive system and on fertility?
Answer:
Endometrosis could negatively affect the probability of gestating an embryo if they are growing inward. The affection of the fallopian tubes and the uterus could alter the implantation or even generate complications for the embryo during pregnancy.
In addition, endometriosis generates painful conditions in the abdominal area to the point that it is considered as menstrual cramps during menstruation, women who suffer from this disease suffer a lot during the menstrual cycle.
Regarding the reproductive system, those female reproductive systems that suffer from this disease are considered potentially malignant, since many malignant neoplasms are incited to appear in these foci of excessive proliferation of the endometrium.
Explanation:
Endometriosis can affect the walls of the fallopian tube and the uterus, since it occurs in the endometrium, that is why it bears that name.
The macroscopic appearance of this lesion at the histological level is a tumor nodule, since they are proliferative foci.
Answer:
abnormal tissue growing on the ovaries might affect ovulation, making it harder or impossible for women to get pregnant. The extra tissue may cause pain, since the tissue is growing in places it is not meant to be growing

The immune response of a host against an invading bacterium is often triggered by surface components on the bacterium that are recognized as "non-self" or "foreign" by the host. These non-self components, often protein or polysaccharide in nature, are referred to as antigens. The host responds to these antigens by making antibodies that will react with invading bacteria and mark them or tag them for destruction by phagocytes.
Indicate the bacterial structures that are likely to be antigens, to which host antibodies bind, marking the invader for phagocytosis
a. fimbriae
b. ribosomes
c. cell wall
d. plasmids
e. flagella
f. capsule
g. nucleoid
Answer:
The correct answer is :
a. fimbriae
e. flagella
c. cell wall
f. capsule
Explanation:
There are several bacterial structures that are binds to the host cells and likely to be antigens to which specific antibodies attached to mark or destruct them by phagocytes.
These bacterial structures are common in the fact that all these structures have binding ability to the host cells and invading them some of these structures are : fimbriae, cell wall, flagella, and capsule that are attached to antibodies and cell of the host.
Thus, the correct answer is :
a. fimbriae
e. flagella
c. cell wall
f. capsule

How are the proteins inside your body affected by the presence of water and other molecules?
Answer:
Our body is constitute of several essential molecules such as proteins, fat, carbohydrate, water, and other molecules.
Each molecule has some of the impact of other molecules in the body. Impact of water and other molecules on proteins inside the body are as follows:
Proteins have ligand-binding site and water provide stability to the ligand-binding site of proteins through its hydrogen bonds.Conformational flexibility and transitions of proteins are due to the presence of water molecules in it.Disbalance in the pH of body due to changing concentration of sodium-potassium ions can denature the protein. Enzymes present in the body can control the rate of formation of proteins in the body.

If the study on the relationship between W. bancrofti and Wolbachia is correct, then combined with the results of the trials, significant numbers of microfilariae do not survive in circulation beyond what time period
Answer:
6 months
Explanation:
First, we must remember that doxycline has an effect only on nematodes, but it cannot effectively prevent microfilariae presented before treatment in the blood of the infected. What we can conclude from this is that it is possible that microfilariae grow and develop, however they will not be able to reproduce, since W. bancrofti is completely dependent on Wolbachia for replication. With that, the microfilariae are running out of time and with about 6 months the patients are free of any trace of microfilariae. So we can conclude that 6 months is the longest time that microfilariae survive in circulation.

According to the graph, which statement below is true?
A. This enzyme works equally well at all temperatures.
B. This enzyme works best at 10 degrees Celsius.
C. This enzyme works best at 45 degrees Celsius.
D. This enzyme works best at 60 degrees Celsius.
The rate of enzyme activity is at its highest when the temperature is 45°C. Thus option C is correct.
What are the factors affecting enzyme activity ?The optimum temperature for most of the enzymes is between 25-35°C and above 50°C leads to destruction of enzymes
The rate also increases with increased enzyme concentration up to the saturation point
Enzymes work at their optimum pH. The rate of enzymatic reaction depend on substrate concentration.
The accumulation of the products decreases the activity of enzymes, as they combine with the active site of enzymes by forming a loose complex and inhibits the activity of enzymes.
Some chemical substances like co-factors, potassium ion (K⁺), manganese ion (Mn²⁺) can increases the enzyme activity.
water increases the reaction rate. Light increases the reaction rate in some enzymes but harmful radiation like UV rays and X-rays decreases activity.

How is genetic information preserved during the copying of DNA? View Available Hint(s) Hint 1.opened hint How is genetic information preserved during the copying of DNA? The information is preserved because DNA codes for RNA, which codes for protein. Genetic information is preserved in the linear sequence of the building blocks A, T, G, and C. Genetic information is preserved by base pairing between A and T and between G and C across the two strands of the double helix. The information in DNA is copied into RNA, which is used as a template to copy back to DNA.
Answer:
Genetic information is preserved in the linear sequence of the building blocks A, T, G, and C.
Explanation:
Deoxyribonucleic acid contains genetic information in the bases i.e the Nitrogenous bases Adenine, thymine, Guanine, cytosine are the store for coding genetic information, in them lies the genetic information of an organism. Each base is coding for different gene the is found in the organism.
After the information on the DNA have been moved to an intermediary Ribonucleic acid (RNA) it is been translated into an amino acid a building block of protein containing all the genetic information coded for by the Nitrogenous base.

Answer:
shoulda used ziploc?
Explanation:
Answer:
Hypotonic
Explanation:
When sugar is dissolved into the water, it adds molucules, making the water have a higher concentration. If you have a semipermable membrane between the two, it would create a process called osmosis. The hydrogen bonds would all go to the side with the higher concentration side, also known as the hypertonic side. The side with less bonds would be called the hypotonic side.

Can podocyte cells in the Bowmann capsule attach to any other basement membrane other than the glomerular basement membrane? That is, it can itself have a separate layer of base membrane?
Answer:
"Podocytes are cells in the Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus. Podocyte cells make up the epithelial lining of Bowman's capsule, the third layer through which filtration of blood takes place.[1] The Bowman's capsule filters the blood, retaining large molecules such as proteins while smaller molecules such as water, salts, and sugars are filtered as the first step in the formation of urine. Although various viscera have epithelial layers, the name visceral epithelial cells usually refers specifically to podocytes, which are specialized epithelial cells that reside in the visceral layer of the capsule.
