Answer:

Bacteria. These one-cell organisms are responsible for illnesses such as strep throat, urinary tract infections and tuberculosis.

Viruses. Even smaller than bacteria, viruses cause a multitude of diseases ranging from the common cold to AIDS.

Fungi. Many skin diseases, such as ringworm and athlete's foot, are caused by fungi. Other types of fungi can infect your lungs or nervous system.

Parasites. Malaria is caused by a tiny parasite that is transmitted by a mosquito bite. Other parasites may be transmitted to humans from animal feces.

Describe how you are involved in both the carbon and oxygen cycles

iragen [17]

Plants use carbon dioxide in a process known as photosynthesis. During photosynthesis, plants give off oxygen as a waste product. Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant's leaves. Oxygen moves out of the plant leaf through these same openings.

Each of the four pedigrees that follow represents a human family within which a genetic disease is segregating. Affected individ

Ne4ueva [31]

Answer:

The following four traits are -:

Pedigree 1 - A recessive trait (autosomal recessive) is expressed by pedigree 1.
Pedigree 2- Recessive inheritance is defined by Pedigree 2.
Pedigree 3 - The inheritance of the dominant trait (autosomal dominant) is illustrated by Pedigree 3.
Pedigree 4- An X-like dominant trait is expressed by Pedigree 4.

Explanation:

Explaination of each pedigree chart-

Pedigree 1 demonstrates the recessive trait since their children have been affected by two unaffected individuals. If the characteristics were X-linked, in order to have an affected daughter, I-1 would have to be affected. $X^A$ In this, both parents are autosomal recessive trait carriers, so the child will be affected by a 1/4 (aa)
Recessive inheritance is defined by Pedigree 2. This is X-related inheritance as autosomal recessive inheritance has already been accounted for in part 1. This inference is confirmed by evidence showing that the father (I-1) is unaffected and that only the sons exhibit the characteristic in generation II, suggesting that the mother must be the carrier. The individual I-2 is a carrier for this X-linked trait. A typical Xa chromosome is attached to the unaffected father (I-1), so the chance of carrier II-5 is 1/2. Probability of an affected son = 1/2 (probability II-5 is a carrier) x 1/2 (probability II -5 contributes ( $X^A$ ) x 1/2 (probability of Y from father II-6) = 1/8. An affected daughter's likelihood is 0 because a typical $X^A$ must be contributed by II-6.
The inheritance of the dominant trait is demonstrated by Pedigree 3 because affected children still have affected parents (remember that all four diseases are rare). The trait must be autosomal dominant because it is passed down to the son by the affected father. There is a 1/2 risk that the heterozygous mother (II-5) would pass on mutant alleles to a child of either sex for an autosomal dominant feature.
Pedigree 4 is an X-linked dominant function characterized by the transmission to all of his daughters from the affected father but none of his son. On the mutant X chromosome, the father (I-1) passes on to all his daughters and none of his sons. As seen by his normal phenotype, II-6 therefore does not bear the mutation. An affected child's likelihood is 0.

In the question the pedigree chart was missing ,hence it is given below.

what is the Science of naming and classifying organisms based on structural comparisons and genetic evidence

lara [203]

Answer: The science of naming and classifying organisms based on structural comparisons and genetic evidence, is known as taxonomy, a branch of biology.

Explanation: Taxonomy is very important. By categorizing organisms, this branch of biology helps scientists to exchange vital biological information, and therefore understand the diversity of species in our planet.

When our bodies overcome the offensive tactics of a particular microorganism, this is referred to as? a) therapy. b) colonizatio

ikadub [295]

When our bodies overcome the offensive tactics of a particular microorganism, this is referred to as Resistance.

The body's defense against infection is provided by the immune system, a complex network of organs, cells, and proteins that also safeguards the body's own cells.

Our immune system remembers every germ (microbe) that the immune system has ever eliminated, allowing it to promptly identify and eliminate the microbe if it re-enters the body.

The body contains a number of additional mechanisms in addition to the immune system for defending itself against microorganisms, such as:

The skin acts as a waterproof barrier and secretes oil that has antibacterial qualities.

Lungs: Phlegm (mucous) in the lungs collects foreign particles, and tiny hairs (cilia) waft the phlegm upward so that it can be expelled through coughing.

digestive tract: Most germs can be killed by stomach acid and the mucous lining, which contains antibodies.

Added defenses include the anti-bacterial enzymes found in body fluids like skin oil, saliva, and tears, which can lower the chance of infection. Constant bowel and urinary tract flushing are also beneficial.
