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.

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.
describe how fertility drugs help women to become pregnant
Answer:
Fertility drugs contain FSH and LH, which stimulate eggs to mature in the ovary. Fertility treatments increase a woman's chance of becoming pregnant, although the treatment may not always work. On the other hand, because the treatment boosts the production of mature eggs, it increases the chance of twins or triplets.
Which of the following statements correctly state(s) the location or function of the cells in the epidermis and dermis? Select all that apply. Keratinocytes are located in the stratum basale in the epidermis and the hair follicle of the dermis.
Answer:
Keratinocytes are located in the stratum basale in the epidermis and the hair follicle of the dermis. This statement is correct.
Explanation:
Keratinocytes are in the stratum basale of the epidermis, which is the deepest layer of the epidermis; from this layer, they ascend to the stratum spinosum, then to the stratum granulosum, then to the stratum lucidum if the skin is thick like the one that is in our hands or soles, and lastly they end in the stratum corneum. While the keratinocytes move from one layer to the next one, they change their characteristics.
Keratinocytes are also in hair follicles, they are similar to the keratinocytes from the dermis, but have some differences, such as their reproduction capacity.
How could a scientist use the scientific method to learn more about the Cretaceous era?
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.Learn more in https://brainly.com/question/19496416

Red-green color blindness is an X-linked recessive disorder that is passed through generations and can be traced by using a pedigree. A pedigree is shown. Sam, Bella, Joshua, and Tim have filled-in shapes. Lisa and Monica have half-filled shapes. Which individuals in the pedigree are identified and labeled carriers for red-green color blindness? Lisa and Monica Sam, Tim, Bella, and Joshua Ben, Jenny, Mike, Carol, Katie, and Chris Ben and Lisa
Answer:
Lisa and Monica
Explanation:
The correct answer would be Lisa and Monica.
For X-linked recessive disorders, a female can be unaffected, a carrier, or affected. However, a male can either be affected or unaffected and never a carrier. This is because females have two X chromosomes while males have only one.
In addition, completely filled-in shapes in a pedigree mean that such individuals are affected for the trait in question while half-filled shapes mean the individuals are carriers for the trait.
Hence, individuals in the pedigree that are labeled carriers for red-green color blindness are Lisa and Monica (they both have half-filled shapes).

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.

Two of the most important and widespread vitamin-derived coenzymes are nicotinamide adenine dinucleotide (NAD) and coenzyme A. ... When NAD loses an electron, the low energy coenzyme called NAD+ is formed. When NAD gains an electron, a high-energy coenzyme called NADH is formed.
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.

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.
