13. Which human characteristic is the result of our genetic material?
a. values
b. gender
c. language
d. personality
Answer:
b
Explanation:
this is because the father has an XY chromosome while the mother has an XX chromosome which is then genetically shuffled to get the offspring
Gender is the result of our genetic material, this is due to the genetic shuffle caused by the father's XY chromosome and the mother's XX chromosome, which results in the progeny, hence option B is correct.
What are sex chromosomes?The X and Y sex chromosomes are present in humans and the majority of other animals. Males have both X and a Y gene in their cells, whereas females have two X chromosomes.
Sperm cells have either an X or Y genome, whereas all egg cells have an X, because of this setup, the male decides the sex.
Since it occurs in people, the XX/XY sex-determination system is the most well-known. The majority of other animals and some insects have the XX/XY system.
Therefore, a chromosome variety known as a sex chromosome plays a role in determining sexual orientation.

Explanation:
What happens if food items with excessive moisture are placed directly into hot shortening?
The excess moisture ( water) in the food items boils up immediately and busts both shortening and water around.
Reaction between hot shortening and waterShortening are known to be fats at room temperature and are usually used in the baking of cakes and bread.
When placed in the temperature that is high, it melts to become liquid.
When you pour a food item that contains excess moisture on hot shortening, the water comes in contact with a higher temperature than the shortening's boiling temperature, so the water starts boiling immediately, and busts both shortening and water around.

Examine the words,
impulse, presynaptic cell, neurotransmitters, receptors, postsynaptic cell,
What idea can be described using all the words listed?
The synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.
What is synapse?It is the functional relationship of contact between the endings of nerve cells.
This communicative process between neurons begins with a chemical-electric discharge in the membrane of the emitting cell (presynaptic cell).
When said nerve impulse reaches the end of the axon, the neuron secretes a substance that lodges in the synaptic space between this transmitting neuron and the receiving neuron (postsynaptic cell), in turn, this neurotransmitter is responsible for exciting another neuron.
Therefore, we can conclude that the synapse is the place where the electrical impulse is modulated, it begins with a chemical-electric discharge in the presynaptic cell and the postsynaptic cell has the receptors that receive and are activated by the neurotransmitter.

Outline seven soil pollutants and state two effects of each of this seven soil pollutants.
[tex]\bold{\huge{\underline{ Answer }}}[/tex]
Soil pollutants are substances which contaminates the soil. Soil pollutants are very harmful substances ,they makes the soil toxic . The presence of these substances in higher concentration directly affects the ecosystem, earth etc.
Here are some major soil pollutants :-1) Industrial wastes
Industrial wastes are the common soil pollutants. The discharge of industrial waste in the soil makes it very toxic and directly affects the growth of plants (agriculture) .Industrial waste also affects the life of some organisms like earth worms which makes the soil more fertile.2) Pesticides
Pesticides are the substances which are generally used to kill the pestes. It includes Insecticides, herbicides and fungicides. The higher concentration of pesticides in cropfield directly affects the human health and responsible for soil pollution, water pollution etc.3) Hydrocarbons
Hydrocarbons are the substances which are composed of hydrogen and carbon. Only some hydrocarbons are responsible for soil pollution as they are very harmful for living organisms. for example the most harmful hydrocarbons is PAHs ( Polycyclic aromatic hydrocarbons) .PAHs in soil affects the growth of plants and it is indirectly responsible for the cancer in humans.4) Metals
Most of the people don't know that the higher concentration of some metals makes the soil very toxic . The concentration of these metals in soil directly kills the human beings and other living organisms.5) Non - biodegradable substances
Most people throw the trash in the soil even they know that soil can't degrade the non - biodegradable substances. When these non - biodegradable wastes eaten by street animals it directly affects the health of those animals and disturbs the ecosystem.6) Human activities
Some people really don't care about the environment. They always do ,what they want to do without even thinking about its consequences on the environment. They throw Cigrattes in the soil, Drop alcohol in soil .These activities makes the soil toxic and the crops that are grown in contaminated soil directly affects the human health.7) Acid rain
It is major reason for the contamination of soil. Some people thought that, It is the natural cause of soil pollution but that's not the reality. Humans are the one's who are responsible for acid rain. Contamination of these acids makes the soil very toxic that it kills the plants on the spot.Answer:
See below.
Explanation:
1) Plastic / Glass:
● Non biodegradable substances & takes a long time to decompose.
● Harmful substances are released into the soil.
2) Acid rain:
● Changes the acid level of the soil.
● Causes harm to the plants, insects & ground water.
3) Pesticides / Insecticides / Artificial fertilisers:
● Alters the health of the soil.
● Causes harm to the plants & the organisms living in the soil.
4) Heavy metals (merculy, arsenic etc.)
● Causes toxic harm to plants & animals.
● Highly poisonous .
5) Industrial wastes:
● pH level of the soil can be altered.
● Makes ground water either too acidic or too basic.
6) Radon:
● Harms microorganisms .
