if you have 6% guanine how much of the other bases do you have? please hurry
100% total of all 4 bases and Guanine and Cytosine need to have 1:1 ratio and Adenine and Thymine need to have 1:1 ratio (This is the Chargaff's rules I think)
6% Guanine must also mean 6% Cytosine
6 + 6 = 12 100 - 12 = 88 88/2 = 44
So 44% of Adenine and 44% of Thymine
During the Human Genome Project, scientists created a gene map showing the relative location of each known gene on every human chromosome. This map led to the discovery that the human genome is made up of about how many genes?
Answer:
Approximately 20,500 genes
Explanation:
The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.

how is a tree a biotic factor
Answer:
You could say the dead tree is now an abiotic factor because biotic factors refer to living things. The tree is no longer living, thus it is not a biotic factor. Alternatively, you could argue that the tree was once living and biotic factors are things that are living or were once living. Thus, the tree is a biotic factor.
What are some similarities between sex-linked traits and dominant/recessive
Answer:
What do you already know about the difference between dominant and recessive traits? Or sex-linked and autosomal traits? Dominant traits are the traits that are normally shown in an organism. Recessive traits are the traits that are not normally shown in an organism overpowered by the dominate trait.

A)
These organisms have homologous structures and therefore have a recent
common ancestor.
B)
The DNA sequences for these two organisms will show 99% homology
since they both code for legs.
The legs of these organisms are analogous structures and do not represent
recent common ancestry.
The donkey and beetle do not share a recent common ancestor because the legs of these organisms have a common purpose but not a common structure.
What is locomotion?A person or object can move from one point to another through locomotion, which is directional movement. Numerous fields of science, medicine, and technology are influenced by the study of locomotion.
In biomimetics (also known as "biomimicry"), which is the creation of man-made procedures, materials, tools, or systems that mimic nature, the mechanisms of locomotion may be used. For instance, designers of robots mimic human movement to produce lifelike androids.
In virtual reality and video game art and design, locomotion is a crucial field of study (VR).
Therefore, The donkey and beetle do not share a recent common ancestor because the legs of these organisms have a common purpose but not a common structure.

Answer:
D. Glycolysis and fermentation metabolize sugars but do not produce
sufficient ATP to sustain life.
Explanation:
its just right trust
The best description of how sugars are metabolized in herbivores that eat clover, which contains high levels of cyanide, is none of the above, which is in Option E, as herbivores that eat clover containing high levels of cyanide may experience a range of symptoms, including lethargy, weakness, and even death.
What is cyanide?Cyanide is a potent toxin that inhibits the enzymes involved in aerobic respiration and the Krebs cycle, which are the primary pathways for metabolizing sugars in animals. As a result, herbivores that eat clover containing high levels of cyanide may experience a range of symptoms, including lethargy, weakness, and even death.
However, some herbivores have evolved strategies to detoxify or tolerate cyanide. For example, some species of rabbits, deer, and cattle have gut bacteria that can break down cyanide into less toxic compounds. These bacteria contain enzymes called cyanide dihydratases that convert cyanide to thiocyanate, which is less toxic and can be excreted in urine. Other herbivores, such as the caterpillar of the cabbage butterfly, can sequester cyanide in specialized tissues and use it as a defense against predators.
Hence, the best description of how sugars are metabolized in herbivores that eat clover, which contains high levels of cyanide, is none of the above, which is in Option E.

Blood type is determined by multiple alleles and can be used to determine the possible parents of an offspring. In this case, the mother has blood type B, and her child has blood type A. There are two possible fathers for this child. The phenotype of one man is type O, and the phenotype of the other man is type AB. What is the genotype of the man who is the father?
A. IAIB
B. IAio
C. ioio
D. IBio
Answer:
A. IAIB
Explanation:
Since the child has blood type A and the mother is B, one man having blood type O makes it so that the child cannot be blood type A.
IAIB is the genotype of the man who is the father.
What are Genotypes?The type of variant present at a specific locus (i.e., region) in the genome is scored by what is known as a genotype. Symbols can be used to symbolize it.
For illustration, BB, Bb, and bb could be used to denote a certain gene variant. The actual DNA sequence, such as CC, CT, or TT, can also serve as a representation of a genotype.
In a single experiment, the genotypes at millions of sites in a genome can be determined using DNA sequencing and other techniques. Some genetics influence an individual's phenotype, or observable traits.
Therefore, IAIB is the genotype of the man who is the father.

Which of the following is an accurate description of a neutral potassium
(K) atom?
19 particles in the nucleus and 39 particles outside the nucleus
39 particles in the nucleus and 19 particles outside the nucleus
19 particles in the nucleus and 20 particles outside the nucleus
39 particles in the nucleus and NO particles outside the nucleus
Answer:
39 particles in the nucleus and 19 particles outside the nucleus
Explanation:
In the atom of every element, there are three subatomic particles namely; proton, neutron and electron that constitutes the behavior of such an atom. The PROTON and NEUTRON are located inside the nucleus while the ELECTRON is located outside of the nucleus.
For instance, in a neutral pottasium (K) atom i.e. uncharged, there are 19 protons and 19 electrons but 20 neutrons. Note that, mass no. = Proton no. + Neutron no. Based on the explanation of the location of each subatomic particle, it means there are 39 particles in the nucleus (20 neutrons and 19 protons) and 19 particles (electrons) outside the nucleus.

Biological diversity, or biodiversity, has become a topic of great concern among conservationists. Biodiversity is often used by scientists and policy makers to help determine the health of ecosystems. (a) Describe TWO characteristics shared by ecosystems that have high biodiversity. (b) Identify TWO specific human activities that result in a loss of biodiversity, and explain how each activity lowers biodiversity. (c) For each human activity you discussed in (b), propose a practical strategy (other than simply banning the activity) to reduce the loss of biodiversity. (d) Describe ONE naturally occurring factor that could lead to a loss of biodiversity. (e) Describe TWO ecological benefits that greater biodiversity provides.
Answer:
Large number of species and abundant resources.
Explanation:
Large number of species and abundant resources are the two characteristics shared by ecosystems that have high biodiversity. Habitat loss and pollution are the two specific human activities that result in a loss of biodiversity. Habitat loss occur when the human removed all the trees and vegetation in order to made the land for cultivation of crops or building houses. Pollution is the main cause that leads to loss of biodiversity. Human activities release gases which pollute the environment and leads to loss of biodiversity. Avoid activities that causes pollution and used of barren lands for cultivation and infrastructure. Climate change is naturally occurring factor that could lead to a loss of biodiversity. Biodiversity boosts ecosystem productivity and natural sustainability.
