Answer: selective breeding
Explanation:
The food components gradually gets digested as food travels through the various components of alimentary canal. The digested food can pass into the blood vessels in the walls of the small intestine. The digestive system consists ofSingle choice.
(a) Digestive tract
(b) Digestive tract and liver
(c)Digestive tract and pancreas
(d) Digestive tract and the associated glands
pls answer
Answer:
(b) Digestive tract and liver
Explanation:
The digestive system consists of the digestive tract and liver. The digestive tract is made up of a large number of parts. These parts include the esophagus, stomach, intestines, rectum, etc. Food enters the mouth and travels down the digestive tract and out passing the rectum. The liver is where the blood passes through and it is responsible for many functions such as the metabolizing of fats and proteins, separating and storing vitamins and minerals, regulating different chemicals found in the blood, etc.

Gray matter White matter
Answer:
- Contains myelinated axons: White matter
- Posterior column: White matter
- Located to the periphery of the spinal cord: White matter
- Gracile fasciculus: White matter
- Anterior spinocerebellar tract: White matter
- Medial vestibulospinal tract: White matter
- Marked by low myelination: Gray matter
- Functions to integrate arriving electrical signals: Gray matter
- Contains somas, synapses, and dendrites: Gray matter
- Tectospinal tract: White matter
- Functions to transmit electrical signals rapidly over long distances: White matter
- Lateral horn: Gray matter
- Ventral horn: Gray matter
Explanation:
Both the brain and the spinal cord contain white matter and gray matter. White matter is the tissue responsible for information transmission (i.e., axons); whereas gray matter is mostly involved in information processing (i.e., neuron bodies). White matter is composed of myelinated axons which extend out from the neuron bodies and glial cells, and this tissue connects different areas of the cerebral cortex (i.e., the outer layer of the brain). Moreover, gray matter is composed of neuronal cell bodies or 'soma' that contain the neuron’s nucleus and unmyelinated axons. Gray matter also has glial cells and capillary blood vessels; whereas white matter also has oligodendrocytes that produce myelin and astrocytes. The color of the white matter is caused by the myelin that surrounds the axons; while the color of the gray matter is due to the capillary blood vessels and neuronal cell bodies. In the cerebrum and cerebellum, white matter is observed in deep areas coated by gray matter; whereas, in the spinal cord, the white matter surrounds the central gray matter. White matter is involved in normal motor and sensory function, this tissue is responsible for learning and coordinating communication between different brain regions. Moreover, grey matter is involved in muscle control and sensory function (e.g., hearing, vision, memory, emotions, speech, decision making, etc).

For Labrador retrievers, black fur is dominant to yellow. a) Explain how two black dogs can have different genotypes. b) Could a black dog have the same genotype as a yellow dog
Answer:
Please find the answers explained below
Explanation:
A) This question involves a Gene coding for fur color in Labrador retrievers (a dog). The allele for black fur (B) is dominant over the alllele for yellow fur (b). Based on the law of dominance by Gregor Mendel, the dominant allele will always mask the phenotypic expression of the recessive allele in a heterozygous state. The two fur colors have different alleles, however, when they come together to form a heterozygote, the black fur is still expressed. Naturally, a black furred Labrador retriever should have the genotype; BB but since the black fur is a dominant trait, another heterozygous genotype will arise as Bb.
B) No, the black dog cannot have the same genotype as yellow dog. This is because the black dog must always have at least one dominant allele (B) in order to be black while the yellow dog, due to the recessiveness of the yellow allele can only have the genotype; bb. Hence, a black dog can either be Bb or BB but a yellow dog can only be bb.

Choose the statement about renewable and nonrenewable energy sources that is NOT true.
a. Renewable energy creates little or no waste and has few negative environmental impacts.
b. There has been little to no recent growth in renewable energy use due to a lack of environmental concerns with the use of fossil fuels.
c. Most nonrenewable energy sources can be renewed, but it takes thousands to millions of years for them to form.
d. New technologies promise future increases in the use of renewable energy sources.
Answer:
b. There has been little to no recent growth in renewable energy use due to a lack of environmental concerns with the use of fossil fuels.
Explanation:
Fossil fuels have had tremendous negative impacts on the environment and humans as well. For that reason, the use of renewable sources of energy, such as hydropower and biomass, have become increasingly popular over the last few decades.
Within our lives, or possibly within many, many lifetimes, the sources of non-renewable energy will run out or cease to exist. The three main fossil fuels that are used as non-renewable energy sources are coal, oil, and natural gas. Carbon is the main element in fossil fuels. Thus, option B is correct.
What best define about nonrenewable energy sources?Fossil fuels have had a terrible impact on both the environment and people. Because of this, the usage of renewable energy sources, such as biomass and hydropower, has risen in popularity over the past few decades.
A natural resource is classified as non-renewable (also known as finite) if it cannot be easily replenished by natural processes at a rate fast enough to keep up with use. Carbon-based fossil fuels are one illustration. The original biological substance can change into a fuel like gas or oil thanks to heat and pressure.
Therefore, There has been little to no recent growth in renewable energy use due to a lack of environmental concerns with the use of fossil fuels.

It is well known that sugars glucose and fructose are the primary fermentable substrates. However, malic acid can also be fermented but to lactic acid rather than ethanol. This is especially important in red wine, why?
Answer:
The correct answer is - due to the different bacteria that produce a different enzyme that is involved in the fermentation of malic acid.
Explanation:
In red wine production, malic acid in present in grapes converted to a softer lactic acid. This process is known as malolactic fermentation. It takes place due to the presence of different types of bacterias such as bacteria of the lactic acid family.
These bacterias produce enzymes which is used to convert the malic acid to lactic acid such a process can occur naturally also.

Provide an argument in favor of the importance for farmers or animal production specialists to understand animal
physiology
Answer:
Its important to understand animal physiology if farmers and animal production specialists wish to meet projected demand for animal products.
Explanation:
They must streamline production and advance capacity to prevent, detect, diagnose, and treat animal diseases. The health and quality of livestock is influenced by genetics, care, nutrition, and environment. The quality of animal products is also affected by production methods and marketing practices.

Would would be the possible gamete combinations?
Answer:
1/4 WR; 1/4 wr; 1/4 wR; 1/4 Wr
Explanation:
The principle of independent assortment indicates how different genes independently separate from one another when gametic (reproductive) cells develop. When a cell divides by meiosis, homologous chromosomes are randomly distributed to daughter cells, thereby different chromosomes segregate independently of each other. In consequence, each gamete has a unique combination of chromosomes. In this case, the two genes are on different homologous chromosomes, thereby gene variants (alleles) will be randomly distributed to daughter cells during meiosis (anaphase I) and thus the expected proportion of gamete genotypes will be 1/4 WR, 1/4 wr, 1/4 wR, 1/4 Wr.

g when hydrogen is present and the citric acid cycle is active, the ph of the mitochondrial matrix is
Answer:
The pH remains constant
Explanation:
The pH value of Mitochondrial matrix = 7.8 while the pH of the intermembrane space of the mitochondria = 7.0–7.4
The presence of the hydrogen atoms makes the mitochondrial matrix acidic and hence reduced the pH value but the pH of inner and outer matrix is maintained equal to each other thus as the H+ ion increases, the base concentration increases thereby pushing H+ to the inter membrane space and hence producing ATP.
