Answer:
the property of living organisms in which they keep their internal systems in balance is called homeostatis. In desert regions, plants have reflective surfaces making them cool, they have several adaptation skills like cactus, where its leaves are spines to reduce transpiration. This happens due to the property homeostatis.
Answer:
Homeostasis is the property of living organisms in which internal systems are kept in balance.
Explanation:
Plants stay cool in the desert heat through their reflective surfaces, reduced leaves, or leaves that are parallel to the sun. Desert plants may also have adaptations that help them store water or very deep roots.
Give the names of two co- enzymes that take part in the cellular respiration.
Answer:
Explanation:
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.

Which macromolecules provide instructions for growth? O A. Lipids O B. Nucleic acids O c. Carbohydrates O D. Proteins
Answer:
B
Explanation:
The macromolecule which provides instructions for growth is nucleic acids. The correct answer is option B.
Macromolecules are large molecules made up of smaller subunits called monomers. There are four main types of macromolecules found in living organisms:
carbohydrateslipidsnucleic acidsproteins.Nucleic acids are macromolecules that store and transmit genetic information. DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are the two main types of nucleic acids. DNA contains the genetic instructions for the development and function of all living organisms, while RNA plays a key role in the process of protein synthesis. When cells divide and grow, they must replicate their DNA so that each new cell receives a complete set of genetic instructions.
Therefore, nucleic acids provide instructions for growth. Option B is the correct answer.

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.

Briefly describe two ways in which the Hardy-Weinberg equation can be used to get information about a population.
Answer:
The Hardy-Weinberg equation can be used to gather valuable information about a population in the following two ways:
1) Estimating allele frequencies: The Hardy-Weinberg equation allows scientists to estimate the frequency of specific alleles within a population. By comparing the observed frequencies with those predicted by the equation, researchers can determine if the population is in genetic equilibrium, meaning that the allele frequencies are stable and not evolving over time.
2) Identifying evolutionary forces: If a population deviates from the expected Hardy-Weinberg equilibrium, it suggests that one or more evolutionary forces, such as natural selection, genetic drift, gene flow, or mutation, are at play. By analyzing these deviations, scientists can gain insights into the factors influencing the genetic makeup of the population and better understand the evolutionary processes driving changes in the population's gene pool.

food is lost as bodily waste?
Answer:
roughly 90 percent of stored energy is lost as waste heat each time
Answer:
In general, roughly 90 percent of stored energy is lost as waste heat each time you go up the food chain by one trophic level. In other words, animals, on average, convert just 10 percent of the energy available from the organisms they eat into stored chemical energy.
Explanation:
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.

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.

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.

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
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.
