Explanation:
The allele of the human transport protein associated with light skin is found almost exclusively in people with European ancestry. The other common allele for darker skin, which appears to be the ancestral allele, is found in people with African ancestry. What is a plausible explanation for how the lighter-skin allele came to be so common in those with European ancestry
Answer:
See Explanation
Explanation:
Darwin's theory of natural selection has it that organisms that are better adapted to their environment happen to survive and reproduce passing on their favorable characteristics to their offspring.
It must have been that a gene mutation occurred in the ancestors of the Europeans which led to the appearance of the allele for lighter skin.
This trait became favorable in their environment and people that had it were able to survive and pass the trait on to their offspring hence it became predominant throughout the population.
List one organism and describe all of its adaptations.
Adaptation is a mechanism of species to survive and reproduce in their environments, adjusting to selective pressures. Cactus: leaves, stems, spines.
What is adaptation?
In biology, adaptation might be defined as the mechanism of organisms to improve their fitness in the environment in which they live, adjusting to different changes and selective pressures acting on them.
Adaptation involves molecular, physiological, morphological, and behavioral changes.
For these changes to persist and be transmitted from generation to generation, they must increase the individual's fitness. They must increase the individual survival and reproductive probabilities, making it more competitive.
A good and easy to unsderstand example of adaptation is the cactus.
Cactusses are plants adapted to dry and hot environments like deserts, where water availability is scarse and temperatures are high.
To avoid dehydration, cactusses have developed wide palmated or cilindirical stems and reduced or vestigial leaves.
They use stem tissues to store water. Vestigial or reduced leaves to avoid transpiration and water loss.As their leaves are not developed, their stems photosynthetize to produce organic compounds.
Some species are very rich in water and nutrients, so they turn to be covetted by other species. Animals living in the same environment look for them as a source of food.
To avoid predation, cactusses have developed large and numeros spines that are leaves modifications. This is another adaptation to avoid being eaten by animals and avoid loosing water through leaves.

An individual who exhibits a mixture of schizophrenic symptoms most likely has undifferentiated schizophrenia. Please select the best answer from the choices provided OT OF
Answer:
True
Explanation:
An individual who exhibits a mixture of schizophrenic symptoms most likely has undifferentiated schizophrenia.
The most likely diagnosis for someone who displays a variety of schizophrenic symptoms is undifferentiated schizophrenia. The aforementioned is therefore True.
What is schizophrenia?The illness that impairs a person's capacity for clear thinking, feeling, and behaviour is schizophrenia. Although the precise origin of schizophrenia is unknown, it is thought that a mix of genetics, environment, and changes in brain chemistry and organization may be at play.
Schizophrenia is characterized as disorganised speech or behaviour, depressed participation in daily tasks, and ideas or experiences that appear disconnected from reality. Memory loss and attention problems could also be present.
Therapy is typically ongoing and frequently consists of a mix of prescription drugs, psychotherapy, and well-coordinated specialty care services.
So, the given statement is True.

Describe the functions and organization of tissue systems in a seed plant.
Answer:
tissues is the protect outer covering of plants
Explanation:
Plants consist of many different types of cells that are organized into aggregates called tissues. Tissues are derived from specialized groups of dividing cells called meristems. Meristems are the source of cells and tissues and therefore they are not strictly speaking tissues themselves
Plants are multicellular eukaryotes with organized tissue and specialized organs with specific tasks.
What are the functions and organization of the tissue system in a seed plant?Plants are multicellular eukaryotes, and their tissue systems are made up of many cell types that serve distinct purposes. Meristematic tissue and permanent (or non-meristematic) tissue are the two main forms of plant tissue systems. Meristems, which are areas of plants that experience continuous cell division and expansion, are where the meristematic tissue's cells may be located. Meristematic tissue cells continue to divide and support plant growth despite being either undifferentiated or incompletely differentiated. Permanent tissue is made up of dormant plant cells, which are no longer actively dividing.Secondary tissues can be simple (made up of similar cell types) or complex (composed of different cell types). Dermal tissue is a simple tissue that covers the plant's exterior and regulates gas exchange. One example of a complex tissue is vascular tissue, which is composed of the specialized conducting tissues xylem and phloem.To learn more about the functions and organization of the tissue system in a seed plant, refer to https://brainly.com/question/17774097

Explain why flask #2 (yeast with glucose) produced more CO2 than flask #5 (yeast with flour). AND how did you know it produced more CO2?
Answer: Glucose
Explanation:
The carbon dioxide produced in the experiment can be directly related to the energy generated after the fermentation process. The carbon dioxide is the byproduct of the chemical reactions in the ethanolic fermentation. Glucose substrate will yield the highest energy along with the highest producer of the carbon dioxide after the fermentation process conducted by yeast as compared to the fermentation process that was conducted by yeast with flour. The flour will offer a source of carbohydrates including starch and sugars. The yeast will find out sugar in the flour and ferment it. Glucose is readily available sugar for the action of yeast so more production of carbon dioxide is expected from glucose substrate.
State one way by which Carbon Dioxide decreases in the atmosphere
Answer:
The early atmosphere was mainly carbon dioxide and water vapour. Water vapour condensed to form the oceans. Photosynthesis caused the amount of carbon dioxide to decrease and oxygen to increase.

How is information for a specific protein carried on the DNA molecule?
a. as a sequence of nucleotides
b. in the double helix shape of the condensed chromosome
c. in the ratio of adenines to thymines
d. as a pattern of phosphates and sugars
Answer:
b
Explanation:
Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. ... In eucaryotes, DNA is contained in the cell nucleus.
The information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Hence, option (a) is the correct answer.
Nucleic acids are of two types. They are namely deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA molecule carries the information for a specific protein. They are described as follows:
DNA is the genetic material of the cell DNA molecules undergo a process called transcription to code for codons on mRNA strand These codons tend to pair with tRNA molecule which holds the amino acids The amino acids will then form a chain in the sequence of DNA nucleotides to result in protein formationThus, we can conclude that the information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Thus, option (a) is the correct answer.

6. Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide. The enzyme increases the rate of reaction, so it is 700 times faster. If the enzyme reaction took 1.9s how long would the reaction take if there was no enzyme? Convert the answer to minutes. Give your answer to 4sf.
Answer:
0.00004524 minute
Explanation:
The enzyme is Catalase, and it speeds up the rate of reaction by 700 times than what it was supposed to be.
If the already sped up rate of reaction is 1.9 seconds, then the initial reaction ought to have taken
1.9/700 seconds and that is 0.0027143 second.
We're asked to convert to minute, we then have
0.0027143/60 which is equal to 0.0000452381 minute.
Since we're asked to round off to 4 significant figure, we have 0.00004524 minute.
