Pollen and Ovules are gametes. How many chromosomes would they have compared to the rest of the plant's body cells? What process made them that way?
Answer:
a. They would have half chromosomes as much as the plants body cells.
b. Meiosis
Explanation:
Gametes are sex cells produced only in sexually reproducing organisms. In plants as stated in this question, male gametes are contained in pollens while female gametes are contained in ovules. The process by which these gametes are made is called MEIOSIS.
Meiosis is a cell division that reduces the chromosomal number of the parent cell by half. This means that each GAMETE will contain half the number of chromosomes as the parent cell. Fir example, if the body cell of a plant contains 30 chromosomes, each gamete formed via Meiosis in that plant will have 15 chromosomes.
In a nutshell, pollen and ovules, which are gametes of plants formed by MEIOSIS would have half chromosomes as much as the plants body cells.

What happens at a cell cycle checkpoint?
Answer:
If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA. If the damage is irreparable, the cell may undergo apoptosis, or programmed cell death 2.

The population of white pines on his land in 2015 was 40. After last weekend the population is 155. Find the growth rate.
Answer:
287.5%
Explanation:
Initial = 40
Recent = 155
Growth rate = ( recent - initial )÷ initial ×100/1
=( 155-40/40) × 100/1
= 115/40×100/1
= 2.875×100/1
= 287.5%
The rate of growth is 287.5%

The acidity of the water in a stream is indicated by its pH. Historically, a certain stream has had a pH of 6.0. Acid rain has caused the stream's pH to become 4.8. Which statement predicts how the stream's ecosystem will most likely be impacted? A The flow rate of the stream will increase B. The flow rate of the stream will decrease. с The number of fish in the stream will increase. D The number of fish in the stream will decrease.
The statement predicts how the stream's ecosystem will most likely be impacted is the number of fish in the stream will decrease. Thus, option D is correct.
What is the procedure to indicate the pH of the water stream?The acidity of the water in a stream is indicated by its pH. Historically, a certain stream has had a pH of 6.0. Acid rain has caused the stream's pH to become 4.8.The flow rate of the stream will decrease. The number of fish in the stream will increase and the number of fish in the stream will decrease.
Acid rain is a form of rain with high concentration of hydrogen ions and is acidic in nature. pH of these rains is low and pH is the negative logarithmic of hydrogen ion concentration. It is known as power of hydrogen.
The animal which has the lowest value of pH will be able to tolerate the acid rain more and will be last to die. From the tolerance range of the animals, frogs has the lowest pH for survival which is 4 and it can bear more acid rain than the rest of the animals will be the last to die.
Therefore, The statement predicts how the stream's ecosystem will most likely be impacted is the number of fish in the stream will decrease. Thus, option D is correct.

What would happen to a deep sea fish brought rapidly to the surface? Explain your answer in light of the fact that gas pressure in the swim bladders of some deep sea fishes increase up to about 300 atmospheres. Also define an atmosphere as it relates to the oceans.
Answer:
Its gas-filled swim bladder explode.
Explanation:
The gas-filled swim bladder of deep sea fish is explodes when brought to the surface too rapidly because in the deep sea there is high pressure on the gases that is present in its tissue so when the fish is brought to the surface too rapidly, the high pressure is removed and the gases that were compressed in the tissue of the fish in deep sea are releases to expand that causes explode of gas-filled swim bladder. There is very high pressure in the atmosphere when we go deep into the sea which put pressure on the lungs of humans and gas-filled swim bladder of fishes which decrease its volume.

Over a period of several decades ecologists conduct an investigation on the survival of a species of lizards
Answer:
To find out the impact of environment on the physical structure of lizard and natural selection.
Explanation:
Ecologists conduct an investigation on the survival of a species of lizards in order to study the impact of environment on the physical body of lizard and natural selection. The ecologists find out that environment has direct impact on the body structure of lizard. Those lizards that spend more time on the ground, have longer legs in order to run fast, while on the other hand, species that lives in the trees usually have shorter legs in order to easily climb on the trees so these body structure helps them in survival and movement.

Texto donde se desarrolle la definicion de seleccion natural. Además, empleem los siguientes terminos: Variabilidad, mecanismo selectivo y Darwin.
Answer:
la selección natural es el mecanismo principal por el cual la evolución ocurre
Explanation:
Charles Darwin fue un naturalista inglés que propuso la teoría de la evolución o 'descendencia con modificación' mediante el mecanismo de selección natural. Acorde a esta teoría, la selección natural se define como el mecanismo selectivo de reproducción diferencial de los individuos mejor adaptados a su ambiente. La variabilidad es el la materia prima sobre la cual la selección natural actúa, seleccionado aquellos individuos que presentan combinaciones fenotípicas y genotípicas más adaptadas para sobrevivir en un ambiente en particular. Los individuos de una población que son 'superiores adaptativamente' poseen más chances de sobrevivir y reproducirse, y por lo tanto tienen también más probabilidades de transmitir sus genes a la siguiente generación.

Describe one method to reduce the air pollutants released from a coal burning power plant
Answer:
A method to reduce the air pollutants released from a coal burning power plant is carbon capture.
Explanation:
Carbon Capture: It separates CO2 from emissions sources and recovers it in a concentrated stream. The CO2 can then be injected into the soil underground for permanent storage, or sequestration. Reuse and recycling can also reduce the environmental effects of coal production and use.
