Answers

It can show because it can be a recessive trait that can be showed up in ones genes. Recessive traits can be less present in parent parents but if both parents have similar recessive traits it can be able to show up in offspring and future offspring. Also it can show in offsprings because of earlier generations. The parents might not have these traits but grandparents are great grandparents might have the traits.

what is traslocation​

Answers

Answer:

The exchange of chromosome segment between non-homologous chromosomes is called translocation.

It is of two types:

Reciprocal translocation

There is an exchange of chromosome segments between two non- homologous chromosomes in reciprocal translocation.

Non- reciprocal translocation

A part of chromosome is translocated from one non-homologous chromosomes to other so that one chromosome becomes deficient and another non-homologous chromosome gains the piece of chromosome and becomes long.

If a plant has a high concentration of minerals inside its root cells, but does not have enough energy for active transport, what could happen to the minerals?

Answers

Answer:

The minerals will not be move or transported to other part of the plants because active transport require energy.

Explanation:

Active transport is a process where molecules and ions are move against a concentration gradient by using energy.

This process require energy, for ions or molecules of minerals to be taken up by plants, it is first moved to the root hairs where they are in high concentration against in dilute concentration on soil Active Transport then occur in the roots where it is taken up to the plants with the use of energy.

If there is not enough energy, active transport will not occur and the minerals will remain in the root hair and will not be move to other part of the plant.

How could a scientist use the scientific method to learn more about the Cretaceous era?

Answers

First, it is necessary that this scientist decide on what point of the Cretaceous period he wants to study. Among several points he may want to study the evolution of microorganisms of that time, the life of a dinosaur species, or the evolution of dinosaurs, the flora that was established during this period, among others. This is the phase of the scientific method called Observation.

After that, he must enter the phase called "Elaboration of hypotheses" where he will raise questions about the point he decided to study. "How many flower species existed in that period?", "How many of these flowers can we observe today?" among others.

After that, he will enter the phase called "Experimentation", where he will establish a type of experiment and all the experimental factors and variables that will allow the hypotheses to be answered.

After the experiment he will collect the data that will be analyzed and that will give results that will answer the hypotheses previously established. This is the phase called "Analysis of the results".

At that moment, he will be able to reach the last phase of the scientific method, the phase called "conclusion", where he will show the conclusions that the experiment allowed to be established.

The Cretaceous period was a prehistoric period that took place between about 140 and 60 million years ago. If a scientist wanted to use the scientific method to learn more about this time, he should implement the following steps:

Identify an unresolved issue or problem that you would like to address. Make a hypothesis that raises answers to these questions or problems. Carry out a series of investigations and experiments dedicated to verifying the hypotheses raised. Finally, having verified the hypotheses, propose a law or rule for the investigated questions.

explain the relationship between crossing over and genetic variation

Answers

Crossing over can create genetic variation. Crossing over is when chromosomes cross over they give + take a part of another chromosome which can create different variation in genes.

Answer:

Crossing over is the process by which genetic material is exchanged by non-sister chromatids during meiosis.  Crossing over results in a new combination of genetic information for the cell for a specific trait.  Crossing over ensures that organisms are not identical from generation to generation.  Genetic recombination allows for a variation in genetic material that is passed through the generations.

C. Nonconservative elements are non-reactive in seawater and have a short residence time.
D. Nonconservative elements are non-reactive in seawater and have a long residence time.

Answers

Answer: Option C.

Nonconservative elements are non-reactive in seawater and have a short residence time.

Explanation:

Non conservative elements are elements that enter the sea water and have little concentrations in the ocean and show spartial variationns. These elements have short residence time I .e short replacement time and they are non reactive .Constituents such as phosphate, nitrate, and other nutrients, and dissolved oxygen, carbon dioxide, etc. are non-conservative because their concentrations are later changed by chemical reaction in the sea.

is Primary Hyperaldosteronism cancer?

Answers

Primary aldosteronism is a group of disorders, originally described by JW Conn, in which there is a non-suppressible secretion of aldosterone and hypertension. Aldosterone is a salt-retaining hormone synthesized by the adrenal gland that is regulated by multiple factors, with the renin-angiotensin system and serum potassium being the major factors. Additional minor regulators include adrenocorticotropic hormone (ACTH), atrial natriuretic factor, and dopamine

Primary hyperaldosteronism can be caused by either hyperactivity in one adrenal gland (unilateral disease) or both (bilateral disease). Unilateral disease is usually caused by an aldosterone producing adenoma (benign tumor) and less commonly by adrenal cancer or hyperplasia (when the whole gland is hyperactive). Bilateral disease is usually caused by bilateral hyperplasia (when both glands are hyperactive). There are rare genetic syndromes like familial hyperaldosteronism type I and II which may cause both glands to be hyperactive.

What are the characteristics of life?

All living things share a number of essential traits or abilities, such as order, environmental sensitivity or responsiveness, reproduction, growth and development, regulation, homeostasis, and energy processing. These qualities help to define life.

Reproduction: In order to be regarded as alive, an object must be able to reproduce and produce children.HeredityHeredity is the capacity of parents to transmit genetic material (DNA) to their children. This can take the shape of genotypic qualities as well as phenotypic traits, which describe how a living thing appears on the exterior.

Cellular OrganizationAll living organisms are organized cellularly and are made up of one or more cells.

Growth and DevelopmentAll living things grow and develop as they age, becoming more physically and psychologically mature.

Adaptation Through EvolutionEvery living thing has undergone some level of evolution, and they all continue to do so in order to adapt to a constantly changing environment.

Response to StimuliLiving things react to environmental stimuli.

Homeostasis A living thing's capacity to maintain steady internal conditions, such as blood pressure, body temperature (thermoregulation), and water balance inside cells, is known as homeostasis.

MetabolismAn organism must use chemical processes to break down and/or use materials from the environment in order to maintain its function, which is known as metabolism.

Some chefs sometimes wrap meat in papaya leaves and the meat is marinated for five hours before it is cooked. What is the purpose of wrapping with papaya leaves? (in biology terms)

Answers

Answer:

See the explanation below.

Explanation:

Marinades serve two different functions: as a tenderizer and flavor enhancer.

Depending on the cut and type of meat, it may need a little assistance to bring it to a palatable range of tenderness. Certain plant and fungi enzymes and acids can break down muscle and connective proteins in meats.

As far back as pre-Columbian Mexico, cooks found that wrapping meats in papaya leaves before cooking made for more tender results. The active enzyme in the papaya leaves is papain, now refined from papayas and commercially available. The connective tissue that comes in direct contact with the protein-digesting enzymes gets broken down. These tenderizing enzymes also reduce the capability of the meat to hold its juices, resulting in greater fluid loss and thus drier meat.
