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?
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.

an error occurs when the DNA of a cell is copied. However, the cell does not divide after the error is detected. which statement best describes the cell cycle for this cell?
a-an error during the G1 phase is corrected during G2 phase
b-an error during the s phase is corrected during G2 phase
c-an error during the G1 phase is corrected during the s phase
d-an error during the s phases is corrected during mitosis
Answer:
An error during the S phase is corrected during the G2 phase.
Explanation:
Why the S Phase Is Important
DNA synthesis must occur rapidly, as the unpaired base pairs of the DNA strand during replication are vulnerable to harmful mutagens, which can lead to genetic abnormalities, cell disease or even cell death
what is traslocation
Answer:
The exchange of chromosome segment between non-homologous chromosomes is called translocation.
It is of two types:
Reciprocal translocationThere is an exchange of chromosome segments between two non- homologous chromosomes in reciprocal translocation.
Non- reciprocal translocationA 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.

explain the relationship between crossing over and genetic variation
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.

Which is one effect that would most likely result from a tsunami?
death
drought
extinction
genetic change
One of the consequences of tsunami happening in a place would be death and destruction of biodiversity.
What is a tsunami?A tsunami is a natural disaster caused by multiple waves in water bodies that send large volumes of water inland.
The sudden displacement of water with a large force destroys lives and properties on land, especially the coastal lands.
Thus, one of the surest effects of tsunamis is death.

A father produces sperm that only carry ‘t’ alleles. What is likely to be his genotype?
Answer:
The Genotype of an organism determines the genetic characteristics of an individual.
If a father produces sperm that carry only 't' alleles, the his genotype will be 'tt' or hom.ozygous genotype.
Hom.ozygous genotype contains the same type of genes responsible for a particular phenotype.
Hence, the correct answer is 'tt' or hom.ozygous genotype.

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)
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.
explain why traits that aren’t present in either parent could show up in the offspring or in future generations of the offspring.
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.

D. No, it is missing the characteristic of responding to stimuli.
Answer:

Explanation:
NO, the rose is missing the characteristic of responding to stimuli, so it's not alive.
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.

is Primary Hyperaldosteronism cancer?
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.
