What is chromosomes ?
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).
What is meiotic cell division ?
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our s.ex cells – sp.erm in males, eggs in females.

Which type of rock is shown in each of these photographs?
In the first image, a sedimentary rock is seen. Sand, mud, and gravel deposits build up over time to produce sedimentary rocks. Typically, these sediments are laid down in layers throughout time, and after being crushed and cemented together, they solidify into rocks.
Due to the variety of sediments that make up sedimentary rocks, these rocks frequently have a layered look. In the second image, an igneous rock is seen. When molten rock, or magma, cools and hardens, igneous rocks are created.
Numerous processes, such as the cooling of lava on the Earth's surface or the crystallisation of magma deep below the Earth's crust, can lead to the formation of these rocks.

Answer:
"The Sun is Earth's main source of energy, making the development of solar power a natural choice for an alternative energy source. Solar radiation is the fundamental energy driving our climate system, and nearly all climatic and biologic processes on Earth are dependent on solar input. Energy from the sun is essential for many processes on Earth including warming of the surface, evaporation, photosynthesis and atmospheric circulation."

The beak size in a species of bird is influenced by a gene for which only two alleles exist. The allele that results in a large beak is dominant to the allele that results in a smaller beak. If introduction of a new food source causes the birds with smaller beaks to be better fit to survive, which of the following will most likely happen?
The allele for small beaks will become dominant to the allele for large beaks.
The bird population will decrease as the recessive allele becomes more common.
The birds with large beaks will die out as a result of lack of food.
The frequency of the allele that results in small beaks will increase.
Answer:
I think that the birds with large beaks will die out as a result of lack of food. (c)
Explanation:
If the smaller birds are better fit to survive then selective pressures should decrease the number of birds with larger beaks.

A. What fraction of the female children will have hemophilia?
B. What fraction of the female children will be carriers?
C. What fraction of the male children will have normal blood clotting?
D. What fraction of the male children will be carriers?
E. What fraction of the male children will have hemophilia?
Answer:
1) A. she gets the X chromosome with the hemophilia gene, she will have hemophilia. A man who has hemophilia and a woman who is a carrier have: a 25% (one in four) chance of having a son with hemophilia. a 25% chance of having a son with normal blood clotting.
2) B. What fraction of the female children will be carriers? 50%.
3) C. a 25% chance of having a son with normal blood clotting.
4) D. What fraction of the male children will be carriers? 07.
5) E. What are the chances of having a child with hemophilia? No sons of a man with hemophilia will have hemophilia. All daughters of a man with hemophilia will be carriers (called obligate carriers). If a carrier has a son, the son has a 50% chance of having hemophilia.

The study of the evolutionary relationships between these structures is known as comparative anatomy. Therefore, the correct option is 3.
What is comparative anatomy?Comparative anatomy is the study of similarities and differences in the anatomy of different species of animals. It involves examining the structures and functions of body parts across multiple species in order to understand the evolutionary relationships between them.
By comparing the anatomical structures of different organisms, scientists can gain insights into their evolutionary history.
Comparative anatomy is also used to identify the evolutionary relationships between different groups of organisms and to help classify them into taxonomic categories. Therefore, the correct option is 3.

What will be the frequency of the recessive allele in a population of 100 kangaroos if there are 50 dominant alleles? (I already tried 0.50 and it was wrong)
A)150
B)0.25
C)0.75
D)0.50
What will the frequency of the dominant allele in a population of 100 tigers if there are 90 dominant alleles?(I already tried 0.9 and it was wrong)
A)0.9
B)0.1
C)0.45
D)0.55
The frequency of the recessive allele in a population of 100 kangaroos in which there are 50 dominant alleles is 0.75 (Option C). It is population genetics.
What is population genetics?Population genetics makes reference to the estimation of genotypic and allelic frequencies in a population.
In this case, the population has 100 kangaroos, thereby there are 200 alleles (50 of which are dominant, i.e., 25% dominant allele).
Moreover, the frequency of the dominant allele in a population of 100 tigers where there are 90 dominant alleles is 0.45 (200 alleles = 100% >> 90 alleles = 45%).

making new organisms

All of the following are functions of asexual reproduction except producing gametes.
What do you mean asexual reproduction?Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.
Asexual reproduction is a type of reproduction in which only one parent is involved. There are basically 5 types of asexual reproduction. These are binary fission, budding, vegetative reproduction, fragmentation and by spores.
The major disadvantages of asexual reproduction are: Lack of diversity- Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent.
