How does thermal energy affect the earth's layers?
Answer:
The thermal energy of the Earth remains from its formation and is continuously generated from radioactive decay of long-lived radionuclides in the Earths interior. The deeper the Earth layers the higher the temperature with the geothermal gradient of temperatures through the Earth’s crust on average as high as 25–30°C/km.
Explanation:
The thermal energy affect the earth's layers by forming a thermal gradient.
Thermal energy of the Earth:
Deep inside the earth the thermal energy is generated by the radioactive decay of long-lived radionuclides.
This creates a thermal gradient from core to surface of the earth. The temperature of the core is highest, then the manle is semi-solid or liquid.
The crust of the earth is solid and have relatively less temperature,
Therefore, the thermal energy affect the earth's layers by forming a thermal gradient.

Why do individuals with recessive
traits show up with less frequency
in populations?
A. There are more dominant alleles in most
populations.
B. Individuals must inherit two copies of a
recessive allele to show the trait.
C. Recessive traits greatly outnumber dominant
traits in most populations.
The individuals with recessive traits show up with less frequency in populations because the individuals must inherit two copies of a recessive allele to show the trait.
What is an allele?"They are the alternative forms of a gene."
What is a recessive trait?It is a trait that is expressed only when the both alleles in the genotype are recessive.The genotype should be homozygous recessive for the trait to appear.What is a dominant trait?A dominant trait is a trait that is expressed even when one parent contributes the dominant allele.It is expressed when the genotype is heterozygous dominant or homozygous dominant.To learn more about recessive, dominant, and populations here,

plz help! What is the specific function of signal cells releasing chemical messages to nearby cells during early embryonic development?
The chemical messages will impact the cells, resulting in change to gene expression.
The chemical messages will facilitate the transfer of mRNA.
The signaling cells will initiate programmed cell death in nearby cells.
The signaling cells will prevent DNA mutation in nearby cells.
Answer: the chemical messages will impact the cells resulting in change to gene expression
Explanation:
The specific function of signal cells releasing chemical messages to nearby cells during early embryonic development is the chemical messages will impact the cells, resulting in a change in gene expression. The correct option is A.
What is embryonic development?The growth and formation of the human embryo are known as human embryonic development or human embryogenesis. It is distinguished by early developmental processes in the embryo, such as cell division and cellular differentiation.
The endoderm, mesoderm, and ectoderm are three germ layers that develop throughout this process, known as gastrulation. Different components of the organism will develop from the cells in these three levels.
Therefore, the correct option is A, The chemical messages will impact the cells, resulting in a change in gene expression.

Black coat is dominant over white coat in guinea pigs. A homo-zygous black pig is mated with another homo-zygous black pig.
What are the genotypes of the parents?
Question 5 options:
bb and bb
BB and bb
Bb and Bb
BB and BB
Answer:
BB and BB
Explanation:
BB is a homo-zygous allele and both of the parent guinea pigs are homo-zygous.
A black coat is dominant over a white coat in guinea pigs. The genotypes of the parents are BB and BB. The correct option is d.
What is a genotype?The terms genotype and phenotype relate to the individual's alleles and the observable traits that are generated from the genotype and determined by the dominance of the alleles, respectively.
For black coat = B
For White coat = b
A homozygous black pig is mated with another homozygous black pig. Homozygous means only one character will be shown in the genotype, that is the dominant and the dominant trait is black, B so, the genotype will be BB and BB. Recessive traits are hidden that do not show, and that is also black.
Therefore, the correct option is d. BB and BB.

2. Animals use oxygen in the process of
make more CO2.
Answer:
Cellular Respiration
Explanation:
As animals breathe, they take in O2 (Oxygen) and exhale in CO2 (Carbon Dioxide). This process is called cellular respiration.
Animals use oxygen in the process of cellular respiration to make more carbon dioxide.
What is Cellular respiration?Cellular respiration may be defined as a type of chemical reaction that involves the breakdown of food in the cell with the release of energy in the form of ATP with the help of oxygen and releases carbon dioxide.
The process of cellular respiration is utilized for the derivation of energy by cells in order to accomplish metabolic activities. This process generally occurs in the animal's cells.
The main purpose of this process is to convert foodstuff molecules into the most usable form of chemical energy known as ATP.
It is opposite to the process of photosynthesis in plants that utilized the carbon dioxide from nature and convert it into glucose and oxygen.
Therefore, animals use oxygen in the process of cellular respiration to make more carbon dioxide.

Compare the stroma and thylakoid in relation to their location in the chloroplast.
Answer:
The stroma is the watery part found in the inner membrane, which contains circular DNA molecules, RNA, ribosomes, lipids, granules of starch, among other substances. The chloroplast genetic process and photosynthesis reactions take place in the stroma. Thylakoids are flattened sacs, or vesicles, that form part of the inner membrane structure of the chloroplast to initiate the light-dependent photosynthesis reaction.
Explanation:
Chloroplasts are typical and exclusive organelles of plant cells that possess chlorophyll. It also has a double membrane (external and internal) and between them an intermembrane space. The inside is filled with a gel called a stroma. The stroma surrounds the thylakoid and grana within the chloroplast. It presents a DNA independent of the nucleus and plastoribosomes. Immersed in the stroma, there are flattened sacs called thylakoids or lamellae, the interior of which is called lumen. Thylakoids can spread throughout the stroma or stack in bundles called grana. Enzyme systems are located in the membrane of grana or thylakoids that capture energy from the sun and carry out the transport of electrons to form ATP.
