Which of the following correctly summarizes the development of the fetus during the second trimester?
Body functions, reflex development, and skin details
Cell division and tissue specialization
Gastrulation, neurulation, and rhythmic breathing
Specialization, function, and growth
Answer:
Body functions, reflex development, and skin details
Explanation:
The second trimester marks the period between the thirteenth to the twenty-sixth week. During this period of fetal development, the fetus begins reflex development such as sucking and swallowing. He is also now able to respond to stimuli.
Body functions are also developing at this stage. The baby can now kick, turn, and move his body. The brains are developing, the hairs and fingernails are also beginning to develop.
Skin details are also developed at this stage. For example, the vernix caseosa is produced to protect the skin of the fetus.

How do bones grow (explain the process)?
Answer:
Bones grow in length at the epiphyseal plate by a process that is similar to endochondral ossification. The cartilage in the region of the epiphyseal plate next to the epiphysis continues to grow by mitosis. The chondrocytes, in the region next to the diaphysis, age, and degenerate.

What type of speciation results in hybrids of the 2 species?
Answer:
Alloploidy results when two species mate to produce viable offspring. In the example shown, a normal gamete from one species fuses with a polyploidy gamete from another. Two matings are necessary to produce viable offspring. The cultivated forms of wheat, cotton, and tobacco plants are all allopolyploids.

A section of one DNA strand has the sequence ACC GAG GTT. What is the sequence of the strand it binds to?
Answer:
UGGCUCCAA
Explanation:
Basically when you transcribe DNA into mRNA, you find the complementing base pair, for example if G is written in the DNA, the mRNA would show C, and if an A was in the DNA, a U would be shown. It is NOT THYMINE in RNA!! This changes to Uracil in RNA, and that is VERY important. The reason why it is flipped is because of the tRNA. So 3 mRNA nucleotides make a codon, and the tRNA are also in sets of 3, but are called anticodons. The tRNA is complementary to the mRNA strand, AKA the same as the DNA strand except with Uracil instead of Thymine. This is because Thymine breaks down in the presence of Oxygen and so is replaced by Uracil.
What happens when a cell becomes too large? List two possibilities.
Answer: As a cell grows bigger its internal volume enlarges and the cell membrane expands the volume increases more rapidly than does the surface area and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.

1Neurons are classified in several different ways. From the following statements, select which ones are true.
The two structural classifications are projection neurons and local inter-neurons.
Function classifications are made up of two subcategories: excitatory and inhibitory.
Histological classification includes bipolar, unipolar, and multipolar.
Classifications using a combination of structural, functional, and neurotransmitter type provide the most robust and useful description.
Classification by neurotransmitter type alone provides the most useful description.
A. I only
B. III only
C. I, II, and V only
D. I, II, III, IV, and V
E. I, III, and IV
Answer:
The correct answer is option D. I, II, III, IV, and V
Explanation:
Neurons are the nerve cells that transmit the information in the form of nerve impulses throughout the body. Neurons are an important part of the body and nervous system as neurons control the movement, any other functions of the body. Classification of neurons is presented on different ways such as structural basis, on the basis of functions, histologically, or on the basis of neurotransmitters used by neurons.
Histological classification - bipolar, unipolar, and multipolar.
Function classifications - excitatory and inhibitory.
structural classification - projection neurons and local interneurons.
All type of classification together makes a robust and very useful description of the neurons.

The mitochondria has been described as the engine of the cell. Why is this a fitting nickname? How is this organelle involved in the process of cellular respiration?
Describe the process of photosynthesis in plants. Why is this process important to animals and humans?
How are the processes of cellular respiration, photosynthesis and carbon cycle related to each other?
Explain how one of the processes discussed in this module (photosynthesis, cellular respiration or the carbon cycle) apply to both the Law of Conservation of Matter and Law of Conservation of Energy.
Answer:
1.Mitochondria is considered as the power house of the cell as it helps in producing large amount of energy in the form of ATP (adenosine triphosphate) that is used in driving various cellular activities.
2.Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!
3.Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
4.Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2). How does photosynthesis demonstrate the law of conservation? ... The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the oxygen and carbon converted.The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle. ... Carbon is used for energy, and some is stored for growth.

The tropical regions are warmer than the polar regions due to the angle of the Sun's rays. As a result, there is generally higher pressure at the poles and lower pressure at the equator, so which way does the wind blow on Earth's surface.... Answers --> A. The wind blows cold air toward the equator from the poles.... B. The wind blows warm air from the poles to the equator..... C. The wind blows cold air from the equator to the poles...... D. The wind blows warm air from the equator to the poles
The wind blows warm air from the poles towards the equator on the surface of the Earth. So, the correct option is B.
What is Wind?Wind is defined as the natural movement of air or other gases relative to a planet's surface which occurs on a variety of scales, from thunderstorms lasting tens of minutes, to land masses lasting a few hours. The wind blows warm air from the poles towards the equator on the surface of the Earth.
Global winds result from differences in the absorption of solar energy between climate zones on Earth, to local breezes that results from the warming of land surfaces. Gentle or moderate wind is known as the breeze while strong and gusty wind is known as the storm, when accompanied by thunder and lightning and small gusts of wind moving at high speed are known as gusts.
So, the correct option is B.

What is the role of digestion?
Answer: Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.
Explanation:
what is the steps of the digestion of protein
Answer:
Protein digestion begins when you first start chewing. There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids.
