1. A certain disorder is recessive and sex-linked. Circle all of the geno-
types of people who have the disorder.
Answers
X^r X^r and X^r Y genotypes of people who have the disorder.
What are genotypes?A genotype is a scoring of the type of variant present at a given location (i.e., a locus) in the genome. It can be represented by symbols. For example, BB, Bb, bb could be used to represent a given variant in a gene.
Moreover, the different types of genotypes are- homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp). The homozygous dominant and the heterozygous genotypes show the same phenotypes.
Hence, there are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells. We all have a specific pair of these hemoglobin in our blood which we inherited from both parents.

2. The text explains that selective breeding involves breeding animals or plants for
specific desirable traits. For example, humans bred different types of dogs to
accomplish certain jobs. Farmers breed chickens for having more meat and laying a
greater amount of eggs. Cattle are often selectively bred either for more meat or for
more milk production. The text also notes that breeding animals for size and strength
interferes with natural animal processes.
Based on this information presented in the text, who benefits from the traits different
animals are bred for?
A. humans breeding the animals
B. the animals being bred by the humans
C. both the humans breeding the animals and the animals being bred by the humans
D. animals not being bred by humans
Answers
Answer:
A. the humans breeding the animals
Explanation:
It says in there that it interferes with the natural animal processes so it probably doesn't help the animal, and it also said in there that we have breed for more desirable traits in other words we bred them to be more useful to us and give us benefits.

How does DNA replication in prokaryotes differ from replication in eukaryotes?
Prokaryotic chromosomes have telomeres, and eukaryotic chromosomes do not.
Prokaryotic chromosomes have a single origin of replication, while eukaryotic chromosomes have many.
The prokaryotic DNA had multiple parts to be replicated, compared to one long chromosome in eukaryotes.
The rate of elongation during replication is slower in prokaryotes than in eukaryotes.

Hello! I have to write an essay based on the Water Cycle and what it is/does. I will give Brainliest for the correct answer. I will also give 20 points to whoever writes the essay, and has the correct answer. Good luck.
Answers
Answer: The water cycle also known as the hydrolic cycle describes the always foward rotation above and below the surfaces of the earth. The mass of water on earths surface remains fairly consistant. However, the water splits up into diffrent groups, freshwater, saline water, ice, and atmospheric water. The water can travel between catorgories such as river to ocean or ocean to atmosphere through evaporation, condensation, precipatation, surface runoff and subsurface flow. When water go through these physical process it can change aswell such as being a liquid, solid,and gas. During evaporation it takes water from it surroundings and cools its enviromwnt,
the exchanges in heat fluctuate the climates tempature.

A population of rabbits in an ecosystem has genetic variation in fur thickness. Some rabbits have thick fur and others have thin fur. Due to changes in the environment, the average temperature of the ecosystem is steadily increasing.
How will this environmental change likely affect the rabbit population over time?
A. Rabbits with thick fur will become more common in the population because thick fur will be a favorable trait in this changing environment.
B. Rabbits with thin fur will become more common in the population because these rabbits are more likely to survive and successfully reproduce.
C. Rabbits with thick fur and thin fur will become equally distributed because all rabbits in the population will successfully reproduce.
D. Rabbits with both fur types will increase in the population because the temperature change will cause the population of rabbits to expand.
Answers
Answer:
B
Explanation:
Thin fur is better for warmer weather, so the rabbits with thinner fur won't over heat in the warming weather.
The population of rabbits n the genetic ecosystem has thick fur and others have thin fur, due to the changes in the climate avg temperature of the ecosystem is steadily falling.
Looking at the situation and adaptive powers or abilities of the animals the thick fur will survive longer than those of the thin fur as the temperature of the place is declining.Hence the option A is correct.

(b) the reproductive cycle involves the production of games
(c) nuclei of sex cells fuse to form a zygote
(d) offspring show much genetic variation
Answers
Answer: 1. Mitosis
2. Answer A.
Explanation:
Stick insects that reproduce asexually are less biologically diverse because they can't evolve as quickly as species that reproduce sexually can. Thus, option A is correct.
What is role of asexual reproduction in evolution?Asexual reproduction, in contrast to sexual reproduction, only contributes to genetic variety in the population if a chance mutation in the organism's DNA is passed on to the progeny.
Evolution can occur gradually. Asexual creatures often evolve relatively quickly following a dramatic mutation and do not need as many generations to accumulate adaptations as do populations that reproduce sexually.
Asexual reproduction has the benefit of allowing for rapid population growth under the right circumstances. You only require one parent. Since you don't require a partner, it is more time and energy efficient.
Therefore, new organisms are usually genetically identical to the parent.

How do your cells know what to do? Just like builders have blueprints to tell them how to build a house, your cells also have instructions. Your cells' instructions are molecules of DNA.
What is DNA?
DNA is the material that makes up our chromosomes and stores our genetic information. When you build a house, you need a blueprint, a set of instructions that tells you how to build. The DNA is like the blueprint for living organisms. The genetic information is a set of instructions that tell your cells what to do.
DNA is an abbreviation for deoxyribonucleic acid. As you may recall, nucleic acids are a type of macromolecule that store information. The deoxyribo part of the name refers to the name of the sugar that is contained in DNA, deoxyribose. DNA may provide the instructions to make up all living things, but it is actually a very simple molecule. DNA is made of a very long chain of nucleotides. In fact, in you, the smallest DNA molecule has well over 20 million nucleotides.
