Answer:
This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed: Example: For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.
This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side: Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.
This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such: Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.
Genes help to define who an individual is inside and out. In addition to visible traits like weight and eye color, psychological qualities such as personality traits, intelligence, risk of mental illness, and more have been linked to genetics.
Explanation:
This is what I could find.
2: gene is a unit of heredity which is transferred from a parent to there kids(offspring). They relate to traits in people because if you’re born tall you got it from your mom/dad or their family traits.

An animal cell with a 30% salt solution is placed in a beaker with a 20% salt
solution. Which is the correct conclusion if the cell remains in the beaker for an
extended period of time?
Answers
Answer:
the animal cell will burst
Explanation:
If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.
Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.
Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.

A)The group that gets only water, no fertilizer
B)The group that gets water and fertilizer
Answers
Answer: The group that gets only water no fertilizer
Explanation:
The control group does not have an additive
The control group will be the group that gets only water, no fertilizer. Thus, option A is correct.
What is function of fertilizer ?
An additional organic or inorganic substances which is added to soil or plants to increase the crop productivity is called as fertilizer.
It contain plant growth promoting nutrients like nitrogen, potassium, and phosphorus; For example, urea, anhydrous ammonia, etc.
The organic fertilizer is derived naturally from plants and animals. It enriches the soil nutrient level, encourage microbial reproduction.
Organic fertilizers are Agricultural Waste, Manure, municipal sludge etc.
Inorganic fertilizers generated chemically contain inorganic nutrients for crop growth; It can be up two types.
Nitrogen fertilizers where nitrogen is the primary element as it is constituent of chlorophyll, maintain the process of photosynthesis, thus improve the crop production.
Phosphorus fertilizer, increases the plant root growth as the protoplasm of the cell contains phosphorus, important for cell growth and proliferation.
Thus, option A is correct.

A student examining an unknown cell under a microscope notes it has a cell wall, cytoplasm, and genetic information contained within a nuclear membrane. Which inference would be correct?
Since the cell possesses a cell wall and genetic information, it has to be an animal cell.
Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.
Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell
Answers
Answer:
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic
Explanation:
Since the cell possesses a cell wall and genetic information, it has to be an animal cell.
-this is a plant cell because of the cell wall
Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.
-prokaryotes don't have DNA contained in a nuclear membrane
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.
- DNA contained in a nuclear membrane --> eukaryototic
- cell wall --> plant cells, which are eukaryotic
Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell
-DNA is contained in a membrane should not lead to the conclusion that it's a plant cell, as it could be an animal cell too
4) How many milligrams are in 1,455 grams?
1,455,000 mg
145,000 mg
1,450 mg
1.45 mg
O
145 mg
Answers
Grams can be converted into milligrams by multiplying the amount in grams by 1000. Therefore, 1455 grams will be equivalent to 1,455,000 mg. Thus, the correct option is A.
The conversion of metric units from one unit to another can be done by multiplication or division by powers of 10. If the unit is to be converted into a bigger unit, it has to be divided, whereas if the unit is to be converted into a smaller unit, it has to be multiplied.
Thus, the conversion of gram to milligram is conversion of a unit into a smaller unit and the amount, therefore, has to be multiplied.
There are 1000 milligrams in 1 gram. Therefore, 1,455 grams will have 1000 × 1,455 = 1,455,000 milligrams.

A company wants to build a new store. After reviewing the piece of land it is determined that a threatened woodpecker nests in that area .If the company is granted permission to build , what is the most environmentally responsible action by the company
Answers
Answer:
Explanation:
If the piece of land is forested or covered with many trees, the company can decide not to bring down all the trees (leaving some trees standing) and move as many as possible nests to the available trees within it's land. This will prevent emigration of the woodpeckers and can ultimately help conserve the woodpeckers in that land and indeed the area in which the land is situated.
This is most environmentally friendly because killing or scaring away of the birds by destroying there homes could lead to imbalance in the environment and even cause gradual extinction of the birds in the environment/area.

for the enzymes responsible for respiration?
Answers
Answer:
30C
Explanation:
One sign that a chemical reaction has taken place is the production of a gas. The more gas bubbles produced, the more reactions that the enzyme is catalyzing.
The highest number of gas bubbles are produced at 30C. The enzymes have the greatest activity in catalyzing chemical reactions at this temperature.
Therefore, this is the optimum temperature for the enzymes in this experiment.

With the boost in warmer weather and excess water, populations will boom
Explanation:
Yabbies will do best at a water temperature of between 12°C and 20°C but they will tolerate water that is a little colder or warmer. Complete immersion in water is not essential for life for the yabby. If its gills are kept moist (humid air is sufficient), it can absorb oxygen from the air and survive for many days out of water. To breed, however, it must be in water. With the water needed for breading and warmer weather used for breeding, population numbers for the Yabbies should rise.
