What is the difference between aggression and courtship?
Answer:
How you approach and talk to the person you like
Explanation:
If you go up and start saying inappropriate things or immediately try to kiss them then that is aggression. But if you go up and give them a subtle and light compliment like ''Hey I like your shirt" and start a conversation, maybe at the end ask (not demand) for her number, then that is a courtship. P.S.If you say something like give me your phone number, that is aggression.

How does passive transport occur?
Answer:
In passive transport, substances move from an area of higher concentration to an area of lower concentration. Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm).

I think it's not because of the water we use it's the water we have.
Explanation:
Because our planet is made up of 75% water it is naturally the first thing to recognize.

A young goat has downward-curved horns. Its father has upward-curved horns while its mother has downward-
curved horns. Which of these statements explains why the young goat has downward-curved horns?
1. The young goat inherited one copy of the gene for horn shape from mother and one copy from its
father. That gene combination instructs for proteins that connect in ways that make downward-curved
horns.
2. The young goat inherited one copy of the gene for horn shape from its mother and one copy from its
father. Those genes connect together to make its downward-curved horns.
3. The young goat inherited its copies of the gene for horn shape from its mother and not from its father.
Just like its mother's genes, those genes instruct for proteins that connect in ways that make its
downward-curved horns.
4. The young goat inherited its copies of the gene for horn shape from its mother and not from its father.
Those genes connect together to make its downward-curved horns.
The young goat inherited its copies of the gene for horn shape from its mother and not from its father.
Those genes connect together to make its downward-curved horns.
Which one is the answer?
Answer:
I think 4 is an accurate answer
Answer:
Explanation:The young goat inherited its copies of the gene for horn shape from its mother and not from its father. Those genes connect together to make its downward-curved horns.

My biology curriculum isn't reliable so I need to ask questions here
1 Why is it important for gametes to be haploid?(1 point)
A) It is impossible for them to be diploid because reproduction does not result in diploidy.
B) They fuse to form a diploid organism so there is the correct number of chromosomes.
C) Neither parent has the full set of genetic information so each must contribute their half.
D) When gametes are made, the diploid cell splits twice, creating four haploid organisms.
2 The inheritance pattern of one gene will not affect the inheritance pattern of another gene. This is known as(1 point)
A) crossing over.
B) genetic variation.
C) random distribution.
D) independent assortment.
3 Which of the following is a difference between phase I and phase II of meiosis?(1 point)
A) Genetic variations can only occur during phase II of meiosis.
B) Phase I results in two diploid daughter cells and phase II results in four haploid daughter cells.
C) Phase I results in daughter cells with 23 chromosomes each and phase II with 46 chromosomes each.
D) Anaphase, metaphase, and telophase only occurs during phase I of meiosis.
4 What is heredity?(1 point)
A) the adaptation of certain individuals that increases their likelihood of survival
B) the passing of genetic information from parents to their offspring
C) the random distribution of chromosomes to produce new genetic combinations
D) the exchange of genetic information to create new variation
5 During meiosis, sister chromatids may exchange sections of DNA leading to genetic diversity. What is this process called?(1 point)
A) karyotypes
B) independent assortment
C) nondisjunction
D) crossing-over
1. It is important for gametes to be haploid because: B) They fuse to form a diploid organism so there is the correct number of chromosomes.
2. When the inheritance pattern of one gene doesn't affect the inheritance pattern of another gene, this is known as: D) independent assortment.
3. A difference between phase I and phase II of meiosis is: B) Phase I results in two diploid daughter cells and phase II results in four haploid daughter cells.
4. Heredity simply refers to: B) the passing of genetic information from parents to their offspring.
5. During meiosis, sister chromatids may exchange sections of DNA leading to genetic diversity in a process called: D) crossing-over.
Gametes are also known to as sex cells and they can be defined as the reproductive cells that are found in a living organism.
It is important for gametes to be haploid cells is because when the sperm and the egg fuse to form a diploid organism, the living sex cells will have 46 chromosomes.Independent assortment refers to a biological process through which the inheritance pattern of a particular gene doesn't affect the inheritance pattern of another gene.
During meiosis, two (2) diploid daughter cells are formed in phase I while four (4) haploid daughter cells are formed in phase II.
Heredity can be defined as the transfer of genetic information (traits) from the parents of a living organism to their offspring, either through sexual reproduction or asexual reproduction.
Some examples of hereditary traits are:
Dimples.Baldness.Height.During meiosis, crossing-over makes it possible for sister chromatids to exchange sections of deoxyribonucleic acid (DNA) which leads to genetic diversity.

IM GIVING 30 POINTS TO WHOEVER ANSWERS THESE
1- how does modern technology provide evidence that all organisms have a common ancestor?
2- what new discoveries about evolution have modern technology made possible?
Answer: 1. Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
2. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species. These members of the species are more likely to reproduce and pass their genes on to their children.
Explanation:
this is an organism whose genome has been altered by the techniques of genetic engineering so that its DNA contains one or more genes not normally found there
Answer:
A transgenic, or genetically modified, organism is one that has been altered through recombinant DNA technology, which involves either the combining of DNA from different genomes or the insertion of foreign DNA into a genome.
The planets, comets, and meteors of the solar system are held
(in orbit by the Sun's.
fa. Gravity
16 Spring force
I. Friction
d. Tension
Answer:
Gravity
Explanation:
Gravity keeps the planets, comets and meteors in orbit around the sun. The sun is bigger and heavier than other planets etc, this causes the planets to be pulled and kept in orbit around the sun.
