Explanation:
A woman with type A blood has a child with type A blood. Which of the following men could NOT be the father
Answer:
B. All males could be the father
Explanation:
A woman with type A blood either has the genotype AA or Ai. A child with type A blood will also either have AA or Ai.
Type B blood is BB or Bi. Type AB blood is AB. Type O is ii.
To find out the men not be the father, you have to do Punnett squares between the mother and father.
AA mother with BB father - type AB child
AA mother with Bi father - type AB and type A child
Ai mother with BB father - type AB and type B child
Ai mother with Bi father - type AB, type B, type A, and type O child
AA mother with AA father - type A child
AA mother with Ai father - type A child
Ai mother with AA father - type A child
Ai mother with Ai father - type A and type O child
AA mother with AB father - type AB and type A child
Ai mother with AB father - type AB, type A, and type B child
According to these crosses, all males could be the father. The father with type B blood must have the genotype Bi. The father with type A blood can have either genotype AA or Ai. The father with type AB blood will always produce a type A child except with a woman who has the genotype BB for type B blood.

Manifestations of osteoarthritis include ( Select all that apply.) nodules on joints of the hands. crepitus with joint movement. pain that is worse upon arising in the morning. stiffness that worsens with joint use. narrowing of joint spaces
Answer:
All options are correct, that is, they would all be correct for osteoarthritis.
This disease is characterized by being very painful at the joint level, it is degenerative, and mobility decreases over time.
Explanation:
Osteoarthritis is a pathology that is based on the fegenerative destruction of the joints, generating edema and loss of function, that is why it is pain.
The pain is very intense and very marked, that is why it is treated with immunosuppressive drugs and analgesics. (In addition to kinesiology and physiotherapy).
This disease decreases the functional unit and the joint space, generating possible ankylosis, pseudoarthrosis, elimination of lubricating fluid from joints and nodular structures. These nodular structures tend to be more common in the hands and are called by professionals as "drum fingers".

. "Horses can swim
faster than dogs" What is the independent variable?
Answer:
See the answer below
Explanation:
The independent variable would be the type of animal (horse or dog).
In the course of an experiment, the independent variable is the variable whose value does not dependent on the value of any other variable in the experiment. It is the variable that the researcher can control during the course of an experiment and whose manipulation changes or influences the actual variable the researcher is set out to measure.
I this case, if an experiment is set up to test the hypothesis that horses can swim faster than dogs, the actual variable that the experimenter would set out to measure would be the speed at which the two animals can swim. As the animals are interchanged for each other, the speed of swimming would vary.
Hence, the type of animal is the independent variable while the speed at which swimming takes place would be the dependent variable.
How do bacterial species build antibiotic resistance? Do viruses do the same thing?
Answer:
When bacteria develop fortifications against the antibiotics that are developed to eradicate them it is termed as antibiotic resistance. Antimicrobial resistance is not only applicable to bacteria, but it is also applicable to other germs like fungi or viruses. There are various ways by which bacteria develop confrontation against antibiotics.
Some bacteria are naturally resilient due to the nonexistence of the target that the antibiotic attacks or due to a remarkably impervious cell membrane. Some of the bacteria possess the tendency to generate enzymes, which can incapacitate antibiotics at the time of acquaintance. In some of the situations, bacteria can change the target of the antibiotics, making the antibiotic inefficient. The generation of efflux pumps in some of the bacteria makes antibiotics to get transport out of the bacterial cell.
The antibiotics are not efficient against viral infections like influenza, colds, bronchitis, the majority of sore throats, and many ear infections and sinuses. The widespread application of antibiotics for these illnesses can generate the spread of antibiotic resistance.

A population of cheetahs has a birth rate of 5 and a death rate of 15. Immigration is 2, and emigration is 4. What is its
population growth?
-14
0 -12
O 12
O 14
Answer:
-14
Explanation:
The population growth is defined as an increase in the number of individuals in a population. The growth of a population depends largely on the birth and death rates as well as migration in and out of the population. Mathematically, the population growth can be expressed as:
(B-D) + (I - E), where B = birth rate, D = death rate, I = immigration, and E = emigration.
In the illustration, B = 5, D = 15, I = 2, and E = 4. Therefore;
Population growth = (5 - 15) + (2 - 4) = (-10) + (-4) = -14
Hence, the population growth is -14.

In the early days of germ theory, contagious diseases were thought to be caused only by fungi or bacteria. In the 1890s, Dmitri Ivanovski filtered extracts from diseased tobacco plants and discovered that the disease could be transmitted to new plants through the filtrate. He hypothesized that something smaller than bacteria or fungi was responsible for the transmission of the disease. Which best explains how Ivanovski's work led to a change in the germ theory? He tried to promote his hypothesis as a law. He used a new experimental method to test his hypothesis. He used a more powerful bacterial strain than other scientists had. He obtained results that confirmed what other scientists were thinking.
Answer:
He used a new experimental method to test his hypothesis.
Explanation:
Dmitri Ivanovski, a Russian microbiologist who was born in the year 1864 and died in 1920. He was the scientist who initiated the discovery of viruses as a pathogenic microorganism. He worked to discover the cause of mosaic disease in tobacco plant and he hypothesized that that something smaller than bacteria or fungi, as early believed, was responsible for the transmission of the disease.
In order to test his hypothesis, he passed a solution containing the causative agent of the disease, which he prepared from the infected plant leaves, through a filter known as Chamberland filter. He was able to discover that the filtrate still contained microbial pathogens that can infect more tobacco plants, confirming his hypothesis that something smaller than fungi or bacteria is responsible for the tobacco mosaic infection.
Hence, to test out his hypothesis, Ivanovski in the 1890's used a new experimental method i.e. CHAMBERLAND FILTER method.

Using your knowledge about the molecular structure of water, explain why ice forms on the top of a lake.
Answer: With my knowledge about the molecular structure of water which states that water is made up of two (2) molecules of hydrogen one (1) molecule of oxygen, ice forms on the top of a lake through a distinct means.
When an Ice forms,the hydrogen atom of one water molecule will then form a weak hydrogen bond with the top of the oxygen atoms of two (2) other of the water molecules.
Thereafter, lining up the water molecules in this designated pattern takes up more space than having them randomly in a jumbled manner just as in the case of water in liquid form.
Small intestine in the site for compelet digestion for carbohydrates,protiens and fats .write down the change happen to the food in the small intestine before its obsorption ??
Explanation:
In the small intestine, enzymes are secreted on the food substances for digestion to take place before absorption in the villi in the small intestine occurs.
For carbohydrates,they are initially called maltose hence the enzyme maltase is secreted on the maltose to convert it into glucose molecules which is needed for the body.
For proteins,they are initially called peptides and polypeptides.An enzyme erepsin is secreted on the peptides and the polypeptides by the small intestine to convert them to amino acids which is also needed by the body.
For fats and oils,they are digested in the duodenum by an enzyme called lipase which coverts them to fatty acids and glycerol before it gets into the small intestine to be absorbed.

Which statements about microevolution and macroevolution is true
Answer: The options are missing from the question.
The options are;
1) Microevolution can lead to macroevolution.
2) Macroevolution can lead to microevolution.
3) Genetic drift cannot affect microevolution.
4) Natural selection only acts on macroevolution.
The correct answer to the question is option 1
MICROEVOLUTION CAN LEAD TO MACROEVOLUTION.
Explanation:
When we talk about microevolution,we are talking about the formation of species via the process of speciation. This formation of species via speciation is made possible by natural selection,a process whereby organisms that are better adapted to their own environment survive in their environment as well as bring about) reproduce new one/species that are similar to themselves. In this process, changes occur with traits but they do so with time. On the other hand, when we talk about macroevolution,we are referring to when major group of organisms form from those groups of species of organisms that are different in a distinct way/manner.
In macroevolution large number of changes occur in the characteristics of the living organisms present,for example, the evolution of entirely new species from the ones that are previously existing. Therefore,we would say that macroevolution is the result of many microevolution processes.
A good example of this is the development of mammals from non-mammalian species or evolution of whales from terrestrial mammals.
Signs and symptoms of aplastic anemia include which of the following? (Select all that apply.) Fever Pallor Dyspnea Petechiae Bradycardia
Answer: FEVER, PALLOR, DYSPNEA AND PETECHIAE
Explanation: Anaemia is the decrease in the quantity and quality of blood cells in circulation in the body.
There are different types of anaemia,one of them being aplastic anaemia.
Aplastic anaemia is a type of anaemia characterised by reduction in the production of enough new blood cells by the body (bone marrow).
When this occurs,the individual becomes easily tired and prone to infection as a result of weakened immune system.
Aplastic Anaemia can be caused by radiation or chemotherapy,it can also be caused by autoimmune reaction when your body starts attacking it's stem cells in the bone marrow.
