So far, we have primarily discussed human adaptations independently of one another. In real life, of course, each person has numerous coexisting ancestral adaptations. Ignore what you know of your family history and consider only your physical traits for the following adaptations: skin color, lactose tolerance, and body shape. Based on these three traits, in what part of the world might your ancestors have originated? Do all three of your traits suggest similar ancestry? Be sure to explain your hypothesized determination using evidence related to all three traits, and be sure to think about all the forces of evolution that might impact your unique history (such as gene flow and founder effect).
Answer:
about skin coloration:
Regarding these modifications, we can say that it influences not only the knowledge of evolution but also on the development of strategies for the management of many diseases, so we know that these changes are not produced by a single agent and factors such as Melanin, a substance produced by melanocytes and which gives the tint to each tone, also includes influences such as exposure to sunlight, both in frequency and geographical area from which it is made. Keratin is also found as its own dermal factor. According to this, there has been an adaptation of the phenotype of each individual mainly to the UV environmental factor that can make changes and modify skin tone.
About lactose tolerance:
It is known that historically, after childhood for many people it was very difficult to continue consuming milk, because the enzyme lactase was not found in them and lactose digestion became very difficult, nowadays it is believed that the weather has influenced to improve digestion
About the body shape:
The inherited factors are very important, from the different habitats of our ancestors, which for reasons of hunting, solar exposure, type of food, were being inherited, today it is known that there are 3 main forms of body types including the endomorph, ectomorph and mesomorph, the main advantages depending on where the individual lives will adapt to persist in the next generation, as well as to use new ways of obtaining food can modify it

A
Animals make minerals, which plants take in through their roots and pass up to their stems.
B
Animals release water vapor when they breathe, which plants take in through their leaves.
C
Animals make their own food, which plants take in through their roots and pass to their leaves.
D
Animals release carbon dioxide when they breathe, which plants take in to help make food.
Answer:
Animals release carbon dioxide when they breathe which plants take in to help make food
Animals release carbon dioxide when they breathe which plants take in to help make food. So the correct option is D.
Why do animals and plants depend on each other?
All species present on earth depend on each other for performing basic life processes. Humans are not able to survive beyond a particular range of temperature and pressure. For all the species to survive, a healthy environment is required.
Plants and animals are dependent on each other. This is because, in ecological systems, no species can survive alone. Animals are dependent on plants. Plants are the primary producers in our ecosystem. They produce food that is consumed by primary consumers and the primary consumers are consumed by secondary consumers.
Plants use carbon dioxide for photosynthesis and it results in the production of oxygen. This is used by animals for the process of respiration.
Plants depend on animals for several reasons. These can be fruit and seed dispersal, pollination, and also for the carbon dioxide that the animals produce. Thus, both plants and animals are interdependent on each other.
Therefore, the correct option is D.

You prepare an agar plate by spread plating & place an antibiotic disk in the middle of the plate. After incubating for a day at 37 degrees C, there are no bacteria on the plate. Which of the following is NOT a reasonable interpretation of what might have happened?
O The bacteria in the culture tube were already dead when you made the plate
O The medium used was defective and provided no nutrition for the bacteria
O The bacteria grew all over the plate but were then killed by the antibiotic
O The spreading tool was too hot when spreading the bacteria
Answer:
A.The bacteria in the culture tube were already dead when you made the plate
Explanation:
Antibiotics are the chemical substance used to kill or stop the growth of bacteria and some other microorganism.
Antibiotics are added to agar plate during experiment for the selection of only those bacteria with resistance to that antibiotic.
There can be several interpretation for the absence of bacteria such as:
The bacteria grows on the nutrients in the medium but due to defective medium they were unable to grow and die.It may also happen bacteria might have grown in all over the plate but due to the action of antibiotic, all the bacteria got killed.Tool used for spreading might kill bacteria as it was hot and bacteria may not be able to tolerate the excessive heat and die.Hence, the only not reasonable interpretation is bacteria in the culture tube were already dead when you made the plate.
So, the correct option is A.

Answer:
Weight of the Jaden on earth is 490 N.
Explanation:
Formula
w = mg
Where w is the weight of an object , m is the mass of an object and g is acceleration of gravity .
Gravity on Earth is 9.8 m/s² .
Jaden’s mass is 50 kilograms.
g = 9.8 m /s²
m = 50
Put the values in the formula
Thus
w = 50 × 9.8
= 490 kg m /s²
(As N = kg m/ s²)
= 490 N
Therefore the weight of the Jaden on earth is 490 N.

ecosystem diversity
none
Answer:
Species diversity is the right answer.
Explanation:
It is stated that the region is full of different organisms. An organism is defined as an individual animal, plant, or single-celled life form. All this variety of a region makes an ecosystem so having multiple ecosystems in a specific region is out of hand.
Identify one process that causes clouds to form in the moist air rising along the frontal boundaries of the low-pressure system.
Answer and Explanation:
The fronts are imaginary lines that separate two air masses of different temperatures. It takes too long for these two masses to mix, causing numerous atmospheric phenomena.
A hot air mass meets a cold air mass. The cold air is heavier and takes a wedge shape under the hot air that rises following a kind of ramp that constitutes the front line.
In the contact area, the hot air cools to the point of condensation and forms clouds that cause precipitation. These warm fronts originate weak but continuous rains.

A true-breeding round, smooth tomato (RRSS) was crossed with a true-breeding long, fuzzy tomato (rrss). All the F1 offspring were round and smooth (RsRs). When these F1 plants were bred there were 43 round smooth offspring and 13 long, fuzzy offspring. Are these two genes likely to be on the same chromosome? Explain.
Answer:
Round, smooth: 43
Long, fuzzy: 13
They are not on the same chromosome because when genes are located on different chromosomes they segregate independently.
How do you know if genes are on the same chromosome?We say that a gene is in linkage or gene linkage when it is on the same chromosome and does not segregate independently at the time of the formation of a gamete. We know that chromosomes are formed by a large sequence of genes that is responsible for determining the characteristics of a species.
Whit this information, we can conclude that they are not on the same chromosome because when genes are located on different chromosomes they segregate independently.

Anya and Greg are working in their research laboratory. Anya tells Greg that one of the mice has a 50% probability of having the alleles DD and a 50% probability of having the alleles Dd. How can Anya explain her reasoning? In two out of 50 times, the mouse has the alleles DD or Dd. The probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd. The mouse is twice as likely to have the alleles DD than it is to have the alleles Dd. There are two more possible outcomes besides the mouse having DD or Dd alleles.
Answer:
Option B: The probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd.
Explanation:
Anya tells Greg that one of the mice has a 50% probability of having the alleles DD and a 50% probability of having the alleles Dd.
She can explain her reasoning by saying that both pairs of alleles (DD and Dd) has equal chance of being expressed i e, the probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd. Both pairs each has 0.5 chance of occuring.
Answer:
Explanation:
A Dominant Allele is an Allele that express itself.
DD- this represent a dominant homozygous allele
Dd- represent a dominant heterozygous allele
When an individual with DD is crossed with Dd we will have DD,Dd,DD,Dd
Phenotypic ratio is 2:2
i.e homozgous dominant crosses with heterozygous dominant
which means both DD and Dd have 50% chance of occuring in the genotype and the probabality is the same.
Note that in the phenotype of an individual with homozygous dominant (DD) is the same phenotype with heterozygous dominant(Dd)

Where is tRNA mRNA and DNA
found in the cell
Answer:
Cytoplasmic tRNAs are found in the fluid inside cells (the cytoplasm). These tRNAs help produce proteins from genes located in the DNA in the nucleus of the cell (nuclear DNA). Although most DNA is nuclear, cellular structures called mitochondria have a small amount of their own DNA, called mitochondrial DNA. and mRNA is found in the nucleus and the cytoplasm in cells.
Explanation:
hope it helps : )
tRNA (transfer RNA) and mRNA (messenger RNA) is found in the cytoplasm of the cell. DNA (deoxyribonucleic acid) is found in the nucleus of the cell.
tRNA plays a crucial role in translating the genetic information carried by mRNA into specific sequences of amino acids during protein synthesis. tRNA molecules are involved in bringing the correct amino acids to the ribosome based on the codons present in the mRNA.
mRNA is synthesized from DNA in the nucleus during a process called transcription. Once produced, mRNA leaves the nucleus and moves into the cytoplasm, where it serves as a template for protein synthesis. In the cytoplasm, mRNA is associated with ribosomes, which are the sites of protein synthesis.
DNA is primarily found in the cell nucleus, where it stores the genetic information of an organism. In some cases, a small amount of DNA can also be found in organelles called mitochondria (in eukaryotic cells) and plastids (in plant cells).
