Explanation:
Water, food, vegetation and shelter are the factors that reduce the population of white-tailed deer due to human involvement in that environment.
Which living and non-living factors affect population?Both living and nonliving limiting factors such as water, food, vegetation and shelter are the factors that reduce the population of white-tailed deer because these factors are now used by humans so there is nothing left for the survival of white-tailed deer.
So we can conclude that water, food, vegetation and shelter are the factors that reduce the population of white-tailed deer due to human involvement in that environment.

Nitrogen is an essential nutrient for plant growth. But farmers who cultivate pulse crops like Green gram, Bengal gram, Black gram etc., do not apply Nitrogenous Fertilizers during cultivation. Why?
Answer:
Nitrogen is so vital because it is a major component of chlorophyll.Nitrogen is the fuel that makes plants go. It's used to synthesize amino acids, proteins, chlorophyll, nucleic acids, and enzymes. Plants need more nitrogen than any other element.Farmers who cultivate pulse crops like green gram, Bengal gram, black gram, etc. do not apply nitrogenous fertilizers during cultivation because these crops have "rhizobium bacteria".
These plants are leguminous plants and they have symbiotic relationship with Rhizobium bacteria. This bacteria converts atmosphere nitrogen in a form that the plant can use, in return the plant provide them shelter and food. That's why they don't need extra nitrogen from fertilizers.

How does carbon cycle through Earth's systems? A. As fossil fuels are burned, carbon dioxide is made available for photosynthesis in animal cells. When the animals die, carbon is released into the soil, and the animal remains form new fossil fuels. B. Animals absorb carbon dioxide through their skin. Dead animals release carbon into the soil. Plants absorb the carbon from the soil and release carbon dioxide during photosynthesis. C. Plants absorb carbon dioxide through their leaves. Animals take in the carbon when they eat the plants. Animals exhale carbon dioxide. Dead plants and animals release carbon into the soilling D. Photosynthesis releases carbon dioxide into the atmosphere Cellular respiration uses carbon dioxide
Answer:
D. Photosynthesis releases carbon dioxide into the atmosphere Cellular respiration uses carbon dioxide.
Explanation:
Carbon dioxide is taken out of the air by the photosynthesis process to make carbon food for crops.
Animals and plants need a mechanism called respiration to remove carbon dioxide gas.
When combustibles are burned, carbon flows from fossil fuels to the air.

Answer:
The awnser would be their DNA is made of different codon sequences.
Explanation:
The reason is Kai gets her sequences from both her mom and dad and so do her parents from their parents and on and on.
The statement that best explains the characteristics of Kai with respect to her parents is as follows:
Their DNA is made of different codon sequences.Thus, the correct option is A.
Why Kai does not appear to be identical to her parents?Kai does not appear to be identical to her parents because of the process known as variation. Variations may be defined as the process of differences in traits of individuals of a progeny from each other and from their parents.
The codon that constructs the characteristics of the DNA significantly depends on the triplet of amino acid sequences that alter the formation of proteins which governs all the properties and mechanisms of living organisms including their appearances.
Therefore, the correct option for this question is A.

B. it has more oxygen
Answer:
B
Explanation:
It has more oxygen blood different after it is pumped through the capillaries in the intestines. Thus the correct option is A.
What is capillaries?Capillaries are delicate blood vessels that exist throughout body. They transport blood, nutrients and oxygen to cells in your organs and body systems. Capillaries are the smallest blood vessels in your vascular system.
Nutrients are absorbed then it goes into the bloodstream through capillaries. These nutrients include acids, vitamins and fatty acids.

ATTGCCATGAAACGCCCCGGTACACCATTGTTCGGCAAATAAAAATAA What is the polypeptide sequence of this sense strand? Use the three letter abbreviation and separate the amino acids with a dash - e.g. Trp-Thr-Ala. If there is a stop codon - you may add an asterisk to the sequence - e.g. Trp-Thr-Ala-*
Answer:
* (Stop) - Arg - Cys - Phe - Ala - Gly - Pro - Cys - Gly - Asn - Lys - Pro - Phe - Ile - Phe - Ile
Explanation:
This question involves gene expression, which consists of transcription and translation. The process of transcription involves synthesis of mRNA from DNA template as follows:
DNA - mRNA
ATT - UAA
GCC - CGG
ATG - UAC
AAA - UUU
CGC - GCG
CCC - GGG
GGT - CCA
ACA - UGU
CCA - GGU
TTG - AAC

Once a standard curve has been prepared by plotting numbers of bacteria (CFU/mL) versus absorbance for one species of bacteria, this curve can be used for estimating bacterial numbers by measuring absorbance for any species of bacteria.
a. True
b. False
Answer:
b. False
Explanation:
The biomechanism of bacterial growth may be examined, by graphing cell growth (also known as absorbance) vs incubation time of the bacteria. A standard growth curve is the result of this process. The amount of turbidity in the broth culture is proportional to the number of microorganisms present.
A standard curve produced for a particular species can't be utilized to predict the number of bacterial counts for a different species due to the listed factors.
The rate of bacterial cell reproduction varies from a particular species to another.Varying species have different absorbance thresholds.How much of your dna do you think is the same as your friends dna ?

(a) Describe why DNA replication is said to be a semiconservative process. Explain how random mutations such as those in pathogens with a mutator phenotype may arise in the DNA of an organism.
Answer:
DNA replication is semi-conservative because each helix that is created contains one strand from the helix from which it was copied. The replication of one helix results in two daughter helices each of which contains one of the original parental helical strands.
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. ... Mutations can also occur as the result of exposure to environmental factors such as smoking, sunlight and radiation.
Btw :
stay safe! :3
(a) In order to understand why the replication of DNA is said to be semi conservative, there is a need to understand what really goes on during replication.
During replication, the two strands of the DNA first become separated.Each strand then makes a complementary copy of itself.The original double strand does not reform, instead, the old strands each forms a double strand by coupling with their newly synthesized complimentary strands.The fact that the 2 double strands DNA that forms at the end of the replication process each consist of one old and one newly synthesized strand is why replication is said to be semi conservative. The old strands remain conserved but are now separated into new double strands.
(b) Random mutations such as those in pathogens with a mutator phenotype may arise in the DNA of an organism due to a host of factors:
mistakes during replicationmutation due to external factors such as chemicals, UV radiation, etc.When this happens, the DNA sequence is altered and this alteration creates one or more phenotypic effects.
