Answer:

to protect you from getting an effaction

to protect you from getting from infection by pathogen is  accurately describes the function of a vaccine​

A vaccine can be defined as a biological preparation which provide an active acquired immunity to a specific infectious and transmissible disease.

A vaccine consist of an agent that has a similarity to the disease-causing microbe. Inactivated Vaccine are formed by inactivating a pathogen by applying heat or chemicals such as formaldehyde or formalin, it destroys the pathogen’s ability to replicate.

Attenuated vaccines are formed from different ways like passing the disease-causing virus through a series of cell cultures or animal embryos.

Toxoid Vaccine can be made by inactivating the toxin released from bacteria that causes disease symptoms, the organisms or viruses used in inactivated vaccines which can be done via treatment with a chemical such as formalin.

Subunit Vaccine use a part of a target pathogen to provoke a response from our immune system, which can be done by isolating a specific protein from a pathogen.

Answer:

Hypotenuse = 7.07 units.

Explanation:

The sides of the right angle triangle are the opposite and adjacent side; which are both equal in this case.

Given the following data;

Opposite = 5 units

Adjacent = 5 units

To find the hypotenuse, we would use the Pythagorean theorem given by the formula;

Hypotenuse² = opposite² + adjacent²

Hypotenuse² = 5² + 5²

Hypotenuse² = 25 + 25

Hypotenuse² = 50

Hypotenuse = √50

Taking the square root of both sides, we have;

Hypotenuse = 7.07 units.

A way I like to remember heterozygous is by remembering that the other word for heterozygous because brainly wont let me say it apparently. The same gender liking each other, so (word) is same, hetero is different.

each square would have 25% each because 100%÷4=25.

Dominant one is like mixing black and blue together,the black is gonna give a dark effect to blue so black is dominant.

Blue is recessive.

The percentage of the Ss is 75% while the percentage of the ss is only 25%.

Given that we have the genotypes of the both parents as Ss. The Ss imples that the gene for short fur is dominant over the gene for long fur.

Now, when we perform te cross for the first generation, we will discover that we have the offspring; Ss, Ss, Ss and ss. The percentage of the Ss is 75% while the percentage of the ss is only 25%.

Explanation:

Flipper of Whale is homologus to the wing of a bird. Homologous organs - The structure which are similar in their morphology, anatomy, genetics and embryology, but dissimilar  in their functions.  

Flipper of whale and wing of bird has similar morphology and anatomy, but differ in their functions according to their species as  well as the habitat where they live in.

A dolphin’s flipper, bird’s wing, cat’s leg, and the human arm are considered homologous structures. Whereas human beings have bones such as the humerus, ulna, radius, wrist bones, and fingers, these features appear as similar bones in form in the other animals.

Answer and explanation:

The mitochondria are the organelle responsible for respiration, which leads to the production of ATP - the most important molecule in energy transfer.

For respiration to happen, there are several processes involving chemical reactions that take place in the mitochondria. These mechanisms are: oxidative decarboxylation, Krebs cycle, and oxidative phosphorylation. Glycolysis is also important for these processes to occur, but this particular case happens outside of the mitochondria.

Pyruvate is an important precursor of the Krebs cycle, also called 'the citric acid cycle'. The researcher observes the functioning of the mitochondria in presence of pyruvate, but then adds an inhibitor of isocitrate dehydrogenase. This inhibitor cancels out the action of the isocitrate dehydrogenase, which is a key enzyme in the Krebs cycle. By inhibiting this enzyme, the cycle cannot continue, and respiration stops.

4.Tissues are groups of similar cells that have a common function. While an organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body.

5.

nervous system - The nervous helps the whole body communicate, our body needs to communicate so we can actually do things like breathing.

respiratory system - The respiratory system gives cells the oxygen they need to survive, and cells keep humans alive. Humans cannot survive without breathing.

digestive system - The digestive system is important for breaking down foods into nutrients, those nutrients are then used to heal and nourish the human body. The digestive system also helps us pass toxic wastes that build up in our bodies, so we don't get sick.

HOPED THIS HELPED!!

Answer:

B

Explanation:

A farmer uses genetic engineering to inject dairy cows with a genetically altered hormone (GAH) to result in the production of more milk, and the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.

The GAHs that are used in dairy farming can result in an increase in the levels of hormones such as insulin-like growth factor 1 (IGF-1) in the milk, and these hormones can be harmful to human health and are also associated with an increased risk of certain cancers, such as breast cancer and In addition to concerns about the health effects of GAHs, there are also environmental concerns. The increased milk production resulting from GAH use can lead to overproduction, and animals get harmed by these genetically altered hormones.

Hence, the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.
