Sperm and egg cells are called [ gametes / zygotes ]
Answers
Sperm and egg cells are known as gametes. Therefore, option A is correct.
What are gametes?A gamete is an animal or plant reproductive cell. Animals' male and female gametes are referred to as sperm and ova, respectively. Each ova and sperm cell carries one copy of each chromosome, making them haploid cells. Meiosis cell division takes place in gametes and it forms four daughter cells.
In humans, gametes are haploid cells with 23 chromosomes—one of each chromosomal pair found in diploid cells—and are hence haploid. The haploid number, commonly known as n, is used to indicate the number of chromosomes in a single pair. n = 23 for people. Sperms are found in the testes and ova are found in the ovaries.
sperm and egg cells are known as gametes. Therefore, option A is correct.

Jack bought a small turtle. Three months later, the turtle had grown to twice its original size. Which of the following statements best describes why Jack's turtle got bigger?
A
Parts of the turtle stretched out as it grew
В
The turtle's cells went through the process of meiosis.
С
The turtle's cells went through the process of mitosis
D
The turtlo's cells absorbed all of the water that it drank
Answers
Answer:
c
Explanation:
The turtle grew twice because its cells went through the process of mitosis. Therefore, option C is correct.
What is mitosis?Mitosis is a type of cell division in which a cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis.
Somatic cells undergo mitosis, which means that all cell types whose function is not the generation of gametes go through this process. Each chromosome is duplicated before each mitotic division, resulting in a full set of chromosomes in the nucleus of each new cell after division.
The turtle grew twice because its cells went through the process of mitosis. Therefore, option C is correct.

Why did the four inner planets of the solar system form as rocky planets and the four outer planets form as gas planets?
Answers
Answer:
The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. In the outer regions of the solar system where it was cooler, other elements like water and methane did not vaporize and were able to form the giant planets.
Explanation:
Answer:
The temperature of the early planetary group clarifies why the internal planets are rough and the external ones are vaporous. In the external districts of the planetary group where it was cooler, different components like water and methane didn't disintegrate and had the option to shape the goliath planets.

Which of the following are TRUE of asexual reproduction
A : All life functions are carried on by cells
B: Requires only one parent
C :Is extremely rare in the
animal kingdom
D: Can only happen by the mother
E: Both plants and animals can do this
Answers
Answer:
Explanation:
Some animals produce offspring through asexual reproduction while other animals produce offspring through sexual reproduction. Both methods have advantages and disadvantages. Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly; these are two advantages that asexually reproducing organisms have over sexually reproducing organisms. In a stable or predictable environment, asexual reproduction is an effective means of reproduction because all the offspring will be adapted to that environment. In an unstable or unpredictable environment, species that reproduce asexually may be at a disadvantage because all the offspring are genetically identical and may not be adapted to different conditions.
what volume will 1.25 liters of carbon dioxide occupy at 50 degrees C if the pressure changes from 0.865 atm to 0.820 atm? show your work!
Answers
Answer:
V₂ = 1.32 L
Explanation:
Given data:
Initial volume = 1.25 L
Initial pressure = 0.865 atm
Final volume = ?
Final pressure = 0.820 atm
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
0.865 atm × 1.25 L = 0.820 atm × V₂
V₂ = 1.08 atm. L/ 0.820 atm
V₂ = 1.32 L

Explanation:
Data was collected concerning Galapagos bird beak size over time. There are several species finches, and they are also known as Darwin's Finches. These finches share the same habits and characteristics except for one; they all have different shaped and sized beaks. The differences in their beaks might be the most important aspect of their survival Around 1977, there was a huge drop in finches vwith small beaks while there was a great increase in large-beaked birds. How can you explain this?
Answers
Answer:
Evolution or Adaptation
Explanation:
Because of the available food in the environment, such as big or small, hard or soft seeds based on the weather and the plant's production, the birds have to adapt to be able to consume their new type of food available, if a bird with a small beak tried to eat a large hard seed, it wouldn't be able to, or if a bird with a big beak tried to eat a small seed, it probably wouldn't be enough

"As you move outwards from a tree there will be more plant growth." Explain why the students thought their hypothesis would be correct.
Answers
Answer and Explanation:
In the case when you move outwards from a tree so there would be more growth, the reasons are as follows:
1. The block i.e. left and light near tree permits lesser photosynthesis as in the tree
2. But if you move outwards so there would be more light
3. Also it permit plants to photosynthesis that generates greater amount of glucose and proteins for growth
In this way it would be explained
