In a sample of double stranded dna if 27% of the nitrogenous bases are thymine what percentage of nitrogenous bases are cytosine
Answer:
23%
Explanation:
According to Chargaff's law A = T and G = C
T = 27%
A = 27%
27 + 27 = 54
100 - 54 = 46
46/2= 23
So 23%
The acidity of the water in a stream is indicated by its pH. Historically, a certain stream has had a pH of 6.0. Acid rain has caused the stream's pH to become 4.8. Which statement predicts how the stream's ecosystem will most likely be impacted? A The flow rate of the stream will increase B. The flow rate of the stream will decrease. с The number of fish in the stream will increase. D The number of fish in the stream will decrease.
The statement predicts how the stream's ecosystem will most likely be impacted is the number of fish in the stream will decrease. Thus, option D is correct.
What is the procedure to indicate the pH of the water stream?The acidity of the water in a stream is indicated by its pH. Historically, a certain stream has had a pH of 6.0. Acid rain has caused the stream's pH to become 4.8.The flow rate of the stream will decrease. The number of fish in the stream will increase and the number of fish in the stream will decrease.
Acid rain is a form of rain with high concentration of hydrogen ions and is acidic in nature. pH of these rains is low and pH is the negative logarithmic of hydrogen ion concentration. It is known as power of hydrogen.
The animal which has the lowest value of pH will be able to tolerate the acid rain more and will be last to die. From the tolerance range of the animals, frogs has the lowest pH for survival which is 4 and it can bear more acid rain than the rest of the animals will be the last to die.
Therefore, The statement predicts how the stream's ecosystem will most likely be impacted is the number of fish in the stream will decrease. Thus, option D is correct.

There is a direct relationship between the number of pollinating plants and the number of honeybees. Each population is dependent on the other for their survival and ultimately reproductive success.
Answer:
Both depends on one another.
Explanation:
Yes, there is a direct relationship between the number of pollinating plants and the number of honeybees because honeybees are insects that are responsible for pollination in the flowering plants. The population of flowering plants also has a great effect on the survival of honeybees because these flowering plants provides food in the form of nectar on which these honeybees survive and make honey from it. So we can say that both flowering plants and honeybees depends on one another for the successful growth and development.

Texto donde se desarrolle la definicion de seleccion natural. Además, empleem los siguientes terminos: Variabilidad, mecanismo selectivo y Darwin.
Answer:
la selección natural es el mecanismo principal por el cual la evolución ocurre
Explanation:
Charles Darwin fue un naturalista inglés que propuso la teoría de la evolución o 'descendencia con modificación' mediante el mecanismo de selección natural. Acorde a esta teoría, la selección natural se define como el mecanismo selectivo de reproducción diferencial de los individuos mejor adaptados a su ambiente. La variabilidad es el la materia prima sobre la cual la selección natural actúa, seleccionado aquellos individuos que presentan combinaciones fenotípicas y genotípicas más adaptadas para sobrevivir en un ambiente en particular. Los individuos de una población que son 'superiores adaptativamente' poseen más chances de sobrevivir y reproducirse, y por lo tanto tienen también más probabilidades de transmitir sus genes a la siguiente generación.

Explain how humans are able to produce one type of hemoglobin as they develop in utero, then produce another to use after birth
Answer:
Hemoglobin F has a different composition from the adult forms of hemoglobin, which allows it to bind (or attach to) oxygen more strongly. This way, the developing fetus is able to retrieve oxygen from the mother's bloodstream, which occurs through the placenta found in the mother's uterus.

In flies, red eye color (Xa) is a sex-linked recessive trait. Black eyes (XA) are the normal colored eyes for flies. What are the chances
that a carrier mom and a black-eyed dad will have (hint: you must use X's and Y's):
a. a red eye male as their next offspring?
b. a black eye female as their next offspring?
2.
3
4.
5 6 7 8 9 10
Answer:
The correct answer is -
a. a red-eye male as their next offspring? = 25%
b. a black eye female as their next offspring? = 25%
Explanation:
The given question says that in flies the red eye color is a sex-linked recessive trait which means it will only appear in the presence of two copies of the recessive allele in females and one copy of recessive allele in male as there is only one copy of X chromosome is present in males the other chromosome is Y.
So, the genotype of carrier mom would be XaXA and normal black eye male would be XAY, then cross between these flies:
XA Y
Xa XaXA XaY
XA XAXA XAY
On the basis of red eye male would be XaY = 1/4 = 25%
and the black eye female would be XAXA = 1/4 = 25%

Which process produces a greater number of offspring?
chromosome duplication
asexual reproduction
gamete formation
sexual reproduction
Answer:
asexual reproduction
Explanation:
Sexual reproduction produces a greater number of offspring compared to asexual reproduction, chromosome duplication and gamete formation.
What is the involvement in sexual reproduction ?This is because sexual reproduction involves the combination of genetic material from two parents, resulting in offspring that have a unique genetic makeup.
This increases the number of possible genetic combinations and thus the number of offspring produced. Chromosome duplication and gamete formation are involved in the process of sexual reproduction, but neither produces offspring by itself.
Chromosome duplication is the process by which one cell splits into two identical cells, each with the same genetic material. Gamete formation is the process by which reproductive cells such as sperm and eggs are formed.
These cells then combine during sexual reproduction to form a new organism. Asexual reproduction, on the other hand, involves a single organism producing offspring that are genetically identical to itself. This means that the number of offspring produced is limited compared to sexual reproduction.

Answer:
Please find the mRNA and amino acid of the DNA sequence in the table below.
Explanation:
This question is describing the processes of transcription and translation. Transcription is the synthesis of mRNA from a DNA template while translation is the synthesis of an amino acid sequence from a mRNA sequence.
The following nucleotides combination are given in this question. Their transcription into mRNA using the complementary base pairing rule is as follows;
DNA = mRNA
- ATG = UAC
- GTA = CAU
- CAA = GUU
- AAT = UUA
- GCG = CGC
- TGT = ACA
- ACT = UGA
- CCC = GGG
- TAG = AUC
Using the codon chart attached as an image, the translation of these mRNA codons is as follows:
mRNA = amino acid
- UAC = tyrosine (tyr)
- CAU = histidine (his)
- GUU = Valine (Val)
- UUA = Leucine (leu)
- CGC = Arginine (Arg)
- ACA = threonine (Thr)
- UGA = STOP codon
- GGG = Valine (Val)
- AUC = Isoleucine (Iso)
