Organisms depend on the environment, which is made of living and nonliving things. The correct option is C.
What is environment?The environment can be defined as the sum of all living and non-living elements and their effects on human life.
Non-living or abiotic elements include water, land, sunlight, rocks, and air, while all living or biotic elements are animals, plants, forests, fisheries, and birds.
Our environment provides numerous benefits, including the air we breathe, the food we eat, and the water we drink, as well as the numerous materials required in our homes, workplaces, and leisure activities.
Healthy ecosystems clean the water, purify the air, maintain our soil in good condition, regulate the climate, recycle nutrients, and provide us with food.
They supply raw materials and resources for pharmaceuticals and other uses. They are the foundation of all civilizations and the backbone of our economies.
Thus, the correct option is C.

Two Drosophila with genotypes AABBCC and aabbcc are crossed to produce a heterozygous offspring, AaBbCc (the gene order is unknown). This AaBbCc Drosophila is crossed with an aabbcc Drosophila, resulting in the offspring below: Number: Phenotype: 600 ABC and abc 200 AbC and aBc 150 ABc and abC 50 Abc and aBC a. Which phenotype represents the double crossovers
Answer:
The double recombinant individuals are less frequent ---> Abc and aBC
Explanation:
We can know if genes are linked, by looking at the progeny distribution. In a tri-hybrid cross, If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, meaning that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.
We can recognize the parental gametes because their phenotypes are the most frequent in the descendants, while the double recombinants are the less frequent. Finally, the simple recombinant gametes are the ones with intermediate phenotypes frequencies.
In the present example, the phenotypic ratio shows different proportions than the expected ones if they were not linked.
We can recognize the parental gametes in the descendants because their phenotypes are the most frequent,
ABC and abc 600while the double recombinants are less frequent.
Abc and aBC 50And simple recombinant gametes produced by the cross, which frequencies are intermediate.
AbC and aBc 200 ABc and abC 150a. Which phenotype represents the double crossovers
The double recombinants are less frequent ---> Abc and aBC
20. Allosteric effectors: a. can cause large changes in enzymatic activity. b. can lead to a decrease in the availability of a protein. c. do not alter the sensitivity of a metabolic pathway. d. decrease the sensitivity of the enzyme at nearly all concentrations of substrate. e. alter enzyme activity by binding to the active site of an enzyme.
Answer:
a. can cause large changes in enzymatic activity.
Explanation:
An enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.
When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy. Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
An allosteric effector can be defined as an agent, organ or molecule that is being binded to an enzyme at a site, thereby causing a reduction (negative effect) or an increase (positive effect) in an enzyme activity.
Hence, an allosteric effector can cause large changes in enzymatic activity because it acts as an intermediary and mediates specific effect in a metabolic pathway.

In cocker spaniels, black coat color ( B) is dominant over red ( b), and solid color ( S) is dominant over spotted ( s). In the F 2 generation of a cross between BB ss with bb SS, what fraction of the offspring would be expected to be black and spotted
Answer:
The correct answer is -3/16
Explanation:
The cross between BBss and bbSS In cocker spaniels will form gametes that are - Bs and bS. As it is given that black coat color ( B) is dominant over red ( b), and solid color ( S) is dominant over spotted ( s) then f1 gen would be :
Bs Bs
bS BbSs BbSs
bS BbSs BbSs
Now F2 generation;
BS Bs bS bs
BS BBSS BBSs BbSS BbSs
Bs BBSs BBss BbSs Bbss
bS BbSS BbSs bbSS bbSs
bs BbSs Bbss bbSs bbss
Here black-spotted that is possible only in two cases, BBss or Bbss, are 3/16

Which of the following reasons for studying botany is most directly related to increased profits?
O Studying botany helps companies develop more abundant food crops for less investment.
O Studying botany can help us keep our forests healthy.
O Studying botany provides a chance to go on to graduate school.
O Studying botany tells us more about our place in nature.
Answer: Studying botany helps companies develop more abundant food crops for less investment
Explanation:
The reasons for studying botany that is most directly related to increased profits was that "Studying botany helps companies develop more abundant food crops for less investment".
Since more food crops are gotten for less investment, it ultimately means that there'll be a reduction in the cost which will hence lead to an increase in revenue and therefore there'll be an increase in profit.

The biodiversity will increase with lower populations of more species.
The biodiversity will decrease with lower populations of more species.
The biodiversity will increase with higher populations of fewer species.
Answer:
The biodiversity will decrease with lower populations of more species.
Explanation:
This is because clearing a forest destroys habitats and therefore kills animals as they have no shelter, no food source and no water source.

As part of a forensic analysis, you have been asked to determine an individual's ancestry using skeletal indicators. The metric measurements you collect indicate that the individual is of European ancestry, but you see several nonmetric traits in the cranium that are typically found in individuals of Asian ancestry. Why might the two methods give different results
Answer:
Due to difference in the methods that is used for analysis.
Explanation:
The two methods give different results because we used two different types of measurements i. e. metric measurement and nonmetric traits. In the metric measurement, we calculate the quantitative character of an individual that gives information about the current status of an individual, while on the other hand, in non-metric traits refers to the method which is used to evaluate genetic connections within and between populations that were present in the past.

If false, please make it a correct statement. A rancher uses a particular chicken for breeding purposes because, on average, she observed that the chicken laid more eggs than other chickens. The rancher selecting the desirable trait would be considered an example of natural selection.
a) true
b) false
Answer:
b) false
Explanation:
The given statement is false. the selection process used by the rancher is an example of artificial selection and not natural selection.
Artificial selection is defined as the selection process done by humans on the basis of desirable characters while in natural selection the selection is based on the adaptive characteristics of animals. In the given example rancher choses a desirable character of chicken that lays more eggs.
Hence, the given statement is "false".

Why do stems have bark? What does the phloem do?
Answer:In old stems the epidermal layer, cortex, and primary phloem become separated from the inner tissues by thicker formations of cork. Due to the thickening cork layer these cells die because they do not receive water and nutrients. This dead layer is the rough corky bark that forms around tree trunks and other stems.

B. It is the site where mRNA codons and tRNA anticodons meet.
C. It is the site where a protein strand is folded into its correct shape.
D. It is the site where proteins are packaged and sent where they are needed.
Answer:
Ribosomes are the sites in a cell in which protein synthesis takes place. ... Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.
