C.testes
D.vas deferens
Answer:
C
Explanation:
You could literally search that up. It's correct though.
"Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells. During puberty, testosterone and other hormones cause these cells to transform into sperm cells."

Explain how a change in the environment can cause the disappearance of traits or possibly cause an extinction of a species.
Answer:
Changes in the environment may leave individuals less well adapted to compete successfully for resources such as food, water and mates. Sometimes an entire species may become unable to compete successfully and reproduce. These problems can lead to extinction.

Claim: Yellow color is always an adaptive trait in a yellow environment.
Do you agree or disagree with this claim?
Yellow color is always an adaptive trait in a yellow environment I agree with this claim.
What is adaptive trait?Adaptive trait is defined as an element of the developmental pattern that makes it easier for its carrier to survive and/or reproduce in a succession of different situations.
Any heritable characteristic that enables a plant or animal to survive and procreate in its environment is referred to as an adaptation.
The process of modifying behavior, physiology, or structure to make it more suitable to an environment is known as adaptation.
It might also be described as the condition that a biological population has achieved after enduring modifications or changes.
There are three types of adaptive traits.

Explanation:
Which of these organisms will be hunted more often by predators when the corn is infected by fungus?
A. Grass
B. Owl
C. Rabbit
D. Snake
Answer:
A. Grass
Explanation:
In their natural habitat, organisms feed on one another in a relationship called PREDATION. Predation involves two organisms; one called the PREDATOR (the organism that eats) and the other PREY (the organism being eaten).
Organisms preying on one organism will naturally opt for a substitute once the previous prey is no longer accesible. This is the case of a fungus-infected corn that is no longer edible for predators. Hence, the predators will hunt similar feed, which is GRASS in this case.

In meiosis II, _____. View Available Hint(s) In meiosis II, _____. chromosomes cross over to exchange genetic information chromosome number is reduced from diploid to haploid homologous chromosomes pair to ensure their even distribution to daughter cells sister chromatids are separated
Answer:
The correct answer is - sister chromatids are separated.
Explanation:
Meiosis is divided in two parts meiosis I and meiosis II. In the later part that is meiosis II is characterized by forming four haploid gametes by separating the sister chromatids in the two daughter cell.
Crossing over takes place in meiosis I that leads to recombination and reduces the chromosome number from diploid to haploid homologous chromosomes and then enters into meiosis II.

Why did DNA technology lead to more use of cladistics?
A. It showed that the Linnaean system was very accurate.
O B. It showed that most traits result from genetic drift.
O C. It showed that different looking animals are actually related.
OD. It showed that gene flow happens between populations.
SUBMIT
Answer:
The correct answer is - C. It showed that different-looking animals are actually related.
Explanation:
DNA technologies help in developing the lineage of the organisms and more use of cladistics. DNA techniques help in determining which animals were closely related by studying the genetic change.
It is used to established new evolutionary relationships between different-looking animals as minor genetic changes may lead to morphological changes.
Which planet has a longer day than year?
OVenus
O Neptune
O Earth
Answer:
VENUS
Explanation:
On Venus, one rotation on its axis takes the equivalent of 243 Earth days and the planet's orbit around the Sun takes the equivalent of 225 Earth days.
Answer:
Venus, I think
Explanation:
So outta these three, Venus is the closest to the sun, so the year is the shortest. Venus is also the planet with the longest day averaging at 116d 18h, so I think that's the right one. Sorry if this is wrong

Explain what causes acid rain to form and its negative effects on living and nonliving things.
Answer:
The rain containing excess of acids called an acid rain.
Explanation:
The rain becomes acidic because of harmful gases like carbon dioxide,
sulphur dioxide and nitrogen dioxide which are emitted as smoke from
vehicles and industries. These harmful gases dissolve in rain drops to
form carbonic acid, sulphuric acid and nitric acid respectively.
Effects of Acid Rain
Acid rain makes the water of lakes, ponds and rivers too acidic
due to which fish and other aquatic animals get killed.
Acid rain eats up the leaves of the trees gradually. By losing
leaves, the trees die. Acid rain also damages crop plants in the
fields.
Acid rain damages the metal structures like steel bridges, etc
when it falls on them.
Acid rain damages the surfaces of buildings and monuments made
up of marble.

(1) body cell mutations will cause the cell to die
before it reproduces
(2) the evolution of a species can result from
changes in reproductive cells, not body cells
(3) random changes are repaired by enzymes

Explanation:
Fruits grown in hot climates are usually less sweet than those grown in cooler temperatures. The high temperatures increase the rate of respiration in the plants, thus reducing the sugar content in some fruits. Why does increased respiration in the leaves and stems reduce the sugar content in the fruits of a plant
Answer:
The correct answer is - Sugars produced in the leaves are used as an energy source instead of being stored in fruits.
Explanation:
The high temperature in climate leads to an increase in the respiration rate in the plants so they require more energy in the process.
They produce sugars in the leaves which leads to a decrease in the sugar content in the fruit as energy is the primary focus in such situation to survive in high temperatures.
