how is the oxygen cycle disturbed by deforestation
Answer:
If deforestation is disturbed then the photosynthesis cycle is disturbed, which results in the oxygen cycle being affected. With a decrease in trees, a decrease in photosynthesis occurs, which cause a decline in the oxygen cycle. A decline in the oxygen cycle results in more polluted air.
Explanation:
Without trees, humans would not be able survive because the air would be unsuitable for breathing. Due to deforestation, there would be fewer trees to "clean" the air. Deforestation is the action or process of clearing of forests, or the state of having been cleared of forests.
Trees and plants, in general, produce energy for growth using a process known as photosynthesis. Using light, water and carbon dioxide, a plant produces energy in the form of sugar and releases oxygen into the air.
Deforestation, as well as a rise in the emissions and our global temperature, affects the air that we breathe. This is because all trees take in carbon dioxide and other pollutants which are known to cause a lot of problems in the atmosphere and to humans. This inevitably results in people breathing dirtier and more polluted air that normally wouldn't happen.
Long-term exposure to polluted air can have permanent health effects such as: Accelerated aging of the lungs. Loss of lung capacity and decreased lung function. Development of diseases such as asthma, bronchitis, emphysema, and possibly cancer.
Trees are responsible for taking the carbon from the atmosphere through photosynthesis in order to make energy. This carbon is then either transferred into oxygen and released into the air by respiration or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly higher amounts of carbon dioxide in the air and lower amounts of oxygen. This bad quality air would also be full of airborne particles and pollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide.
In addition to the decrease of oxygen in the atmosphere, it would allow excessive amounts of carbon dioxide to remain. In the short term, since CO2 is one of the major greenhouse gases, it will undoubtedly lead to higher global temperatures which, in turn, would quicken the melting of the polar ice caps.

It is observed that constipation is more common among people in the western countries who eat more meat and processed food than us. What could be the reason for this? What should be changed in their diet?
I already know this answer, just checking, it's cuz of roughage
Answer:
yes your answer is correct
Explanation:
Constipation happens when the colon absorbs too much water, this can occur if the muscles in the colon are contracting slowly or poorly, causing the stool to move too slowly and lose more water. As meat need much water to digest, so they leads to problem of constipation. Hence, they should eat sufficient amount of water to cure constipation.
Constipation is common among people in western countries who eat more meat and processed food because there is no enough roughage in their bodies which prevents constipation .Fruits and vegetables like like corn etc contains lot of roughage.

Discuss the sensory neurons for vision. What are the two
types of sensory neurons for vision? Where are they located?
What are their functions in the eye? What path does visual
input take AFTER reaching the sensory neurons (be specific,
outlining the entire path to the destination point of the brain)?
Answer:
Olfactory sensory neurons (OSN).
Explanation:
Olfactory sensory neurons (OSN) are the sensory neurons that is responsible for vision. Photoreceptors and olfactory sensory neurons (OSN) are the two types of sensory neurons for vision. Both olfactory sensory neurons (OSN) and photoreceptors is responsible for the receiving of photons and enable us to see things. The right half of the visual field will travel in the left optic tract, while on the other hand, the stimuli from the left half of the visual field will pass through the right optic tract.
Answer: The two types of sensory neurones are the CONES and RODS. Their functions are better outlined below
Explanation:
The CONES and RODS are the sensory neurones ( photoreceptors) of the eye which are located in the retina.
The RODS: They are extremely sensitive and can detect light of very low intensity. They also perceive light in black and white. They, therefore, play an important role in dim light.
The CONES: They function in bright light and are responsible for colour vision.
The path visual input take AFTER reaching the sensory neurons is as follows:
--> the rods and cones are stimulated
--> A pattern of electrical impulses is sent to the brain through the optic nerve which interprets it, drawing on past experience.
The brain tells us that the object is upright and gives us it's real size and distance from the eye. We, therefore, see the object as it actually is, and not as the image formed on the retina.

If all 15 presynaptic neurons stimulate the post-synaptic neuron at the same time, will an action potential be produced?
Answer:
Yes
Explanation:
If all 15 presynaptic neurons stimulate the post-synaptic neuron at the same time, the action potential will be produced. In a chemical synapse, an action potential in the presynaptic neuron is responsible for the release of a chemical messenger known as neurotransmitter. After this, the neurotransmitter diffuses across the synapse and binds to the postsynaptic cell so we can say that potential can be produced.

Normal diploid somatic cells of the mosquito Culex pipiens contain six chromosomes. The G1 nucleus of a mosquito cell contains 3.0 x 10^-12 grams of DNA. How much nuclear DNA would be expected in metaphase I of meiosis?
a. 6.0 x 10^-12 g.
b. 1.5 x 10^-12 g.
c. 12 x 10^-12 g.
d. 3.0 x 10^-12 g.
e. 0.75 x 10^-12 g.
Answer:
a. 6.0 x 10^-12 g.
Explanation:
The interphase is the previous step before the cell divission occurs. The interphase is formed of the G1, S, and G2 stages.
• During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
• During the S stage occurs the DNI replication process. It also occurs the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.
• G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
Through the process of Meiosis, a diploid germ cell (2n) divides and originates four daughter cells with a haploid chromosome number (n). Each daughter cell has half of the chromosomes of the original one. Meiosis is completed in two phases. During the first phase, and after replication, occurs the chromosome´s reduction division. During the second phase, the cell suffers a new, not reductive division.
1. In the first phase, Meiosis I:
Prophase I: Chromosomes condensate and became visible. Occurs crossing-over between homologous chromosomes. Crossin-over makes the daughter cells to be genetically different from the original one. Metaphase I: The pairs of homologous chromosomes randomly align in the equatorial plane. Anaphase I: occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. Telophase I: Each of the homologous pairs chromosomes is already in the corresponding poles, and the nuclear membrane forms again in each pole.2. In the second phase, Meiosis II:
Prophase II: Chromosomes condensate again and become visible. Metaphase II: Chromosomes join the spindle apparatus and migrate to the equatorial plane, where they randomly line up. Sister chromatids are holden together until they reach the Anaphase. Anaphase II: Centromeres divide, chromatids get separated, and each of them goes forward an opposite cellular pole. Telophase II: Once in the poles, the chromosomes became lax again, and cytokinesis occurs.In the exposed example, DNI in the G1 nucleus of a mosquito cell still has not suffered replication (3.0 x 10^-12 grams). The replication process occurs during the S stage, which follows the G1 stage. After the S stage, the cell has 6.0 x 10^-12 g of DNI.
During meiosis, the reduction in chromosomes number occurs in anaphase where homologous chromosomes migrate to different poles. But during metaphase I, the cell still has 6.0 x 10^-12 g of DNI.

Explanation:
In mice, apricot eyes is recessive to black eyes. Tail length is governed by another gene, linked to the eye color gene. Long tails is dominant to short tails. To determine the distance between the two genes, a double heterozygote is mated in a testcross and the classes of progeny produced were as follows:
Apricot eyes, Long tails 33
Apricot eyes, Short tails 20
Black eyes, Long tails 17
Black eyes, Short tails 30
Determine whether the heterozygous parent is in the cis or trans arrangement.
a. Cis
b. Trans
Answer:
trans
Explanation:
From the given information:
The study observes the genes present in mice for eye color and tail length. Since both genes are linked, it implies that they exist in the same chromosomes.
Black eyes is dominant over apricot eyes
Let Black eye be B and apricot eyes be b
Long tail is dominant over short tail
Let long tail be L and short tail be l
If double heterozygote(homoozygous-recessive) engage in the testcross
Then:
From the result given:
The parental combinations are:
Apricot eyes, Longtail (bL / bl) = 33
Black eyes, Short tails (Bl / bl) = 30
The recombinant genes are:
Black eyes, Long tails (BL / bl) = 17
Apricot eyes, Short tails (bl / bl) = 20
The recombination frequency relates to the distance between the two genes which can be computed as:
= (20+17)/100
= 37%
Thus; the heterozygous parent is in trans arrangement.
