Explanation:
Steroid Hormone: It is thought that, because of their lipophilic nature, free steroid hormones enter target cells primarily by passive diffusion through the cell membrane. After gaining entry to the cell, steroid hormones act as ligands for nuclear receptors and alter gene transcription
Protein Hormone: Small uncharged molecules can diffuse freely through a phospholipid bilayer. However, the bilayer is impermeable to larger polar molecules (such as glucose and amino acids) and to ions. These molecules pass across membranes via the action of specific transmembrane proteins, which act as transporters.
Water/Ion: Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly. On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.
A substance that will easily pass through the membrane is: B. steroid hormone.
What is a membrane?A membrane can be defined as the thin layer that separates the ineterior of a living cell from another, especially by forming its outer boundary or layers.
This ultimaetly implies that, a membrane provides protection for a living cell or an internal cell compartment from its environment.
In conclusion, a steroid hormone is a substance that will easily pass through the membrane.

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.

A donkey and a beetle both use legs for locomotion, but the donkey has an internal

and beetle? Choose ALL that apply.
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.

La interacción entre soluto y solvente que permite que se forme una disolución se denomina solvatación
Answer:
Verdadero.
Explanation:
En una solución hay un solvente y uno a más solutos. El solvente es el componente que se encuentra en mayor cantidad y que disolverá al soluto. El soluto es el componente que se encuentra en menor cantidad y que se disolverá en el solvente. Para que se forme la disolución, los iones o moléculas presentes en el soluto tienen que ser rodeados por moléculas provenientes del solvente, este proceso se llama solvatación.

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.

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

In pea plants, the allele for smooth pods (S) is dominant over the allele for constricted pods (s).
Which of the following pairs of terms are correctly matched?
Choose 1 answer:
Ss - phenotype; smooth pod - genotype
SS - genotype; constricted pod - phenotype
SS - phenotype; constricted pod - genotype.
SS - genotype; constricted pod - phenotype
Answer:
ss - genotype; constricted pod - phenotype
Explanation:
trust me Lol
Pea plants having gene control phenotype of pod shape S is dominant having phenotype smooth and phenotype constricted pods having s genotype, hence option d is correct.
What is the difference between genotype and phenotype?Phenotype is a physical observation of a trait which control by agene
and genotype is a genetic observation that can not be seen physically.
The allele which controls the phenotypic character of a plant is called the dominant over the other allele which can not show its expression, the allele is always present in a group but only the dominant will show its expression.
In a pea plant, if the allele for smooth is dominant over the other, it shows expression in allelic combination and masks the expression of constricted pods.
Therefore SS is the genotype and the constricted pod is the
phenotype, hence option d is correct.

Calculate the gravitational potential energy of a 1,200 kg car at the top of a hill that is 42 m high.
Answer:
Gravitational potential energy = 493,920 J
Explanation:
Given:
Mass of car = 1,200 kg
Height = 42 m
Find:
Gravitational potential energy
Computation:
We know that;
Gravitational acceleration g = 9.8 m/s²
Gravitational potential energy = mgh
Gravitational potential energy = (1,200)(9.8)(42)
Gravitational potential energy = (11,760)(42)
Gravitational potential energy = 493,920 J

Answer:
C
Explanation:
Because its a chemical reaction or whatever but it's correct
A reaction where the atoms of elements are rearranged is when two isotopes of hydrogen fuse to form helium, which is option D. In this reaction, the atoms of elements (hydrogen isotopes) are rearranged.
The fusion process involves the combination of two hydrogen isotopes, typically deuterium and tritium, to form a helium nucleus. This nuclear fusion reaction is the primary process that powers stars, including our Sun, where hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the process. Deuterium is an isotope of hydrogen that contains one proton and one neutron, while tritium is another isotope of hydrogen that contains one proton and two neutrons.
