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.

Humoral immunity is a type of adaptive immunity that results in the circulation of which of the following throughout the blood?
A. antigens
B. macrophages
C. natural killers
D. antibodies
Answer:
Humoral immunity refers to the component of the adaptive immune response that is caused by B cells, antibodies, and type 2 helper T cells (Th2), as well as circulating mast cells and eosinophils to a lesser extent.
Antibodies is circulated throughout the blood in Humoral immunity.
B cells changed into plasma B cells that is responsible for the production of antibodies against a specific microbe such as bacteria and virus etc. The humoral immune system attacks and controls the antigens that are present outside the infected cells. Humoral immunity is also known as antibody-mediated immunity so it is concluded that antibodies provides immunity in humoral immunity system.

What happen to the brain and the brain cavity?
Answer: OK so The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).Survival in untreated hydrocephalus is poor. Approximately, 50% of the affected patients die before three years of age and approximately 80% die before reaching adulthood. Treatment markedly improves the outcome for hydrocephalus not associated with tumors, with 89% and 95% survival in two case studies

Answer:
cranial cavity
The cranial cavity, also known as intracranial space, is the space within the skull that accommodates the brain. The skull minus the mandible is called the cranium. The cavity is formed by eight cranial bones known as the neurocranium that in humans includes the skull cap and forms the protective case around the brain.
Explanation:
What are TWO factors that could affect the rate of diffusion?
Answer:
Diffusion occurs when particles move from an area of high concentration to an area of low concentration. The factors affecting rate of diffusion are: concentration, temperature, mass of the particle and properties of the solvent in which diffusion occurs. Faster movement equals faster diffusion.

In the space below, discuss some of the advantages and disadvantages of asexual and sexual reproduction. Compare and contrast individuals that are sexually and asexually reproduced. Use complete, meaningful sentences to explain the information you give as your answer.
Answer:
The advantages of sexual reproduction:
produces genetic variation in the offspring
the species can adapt to new environments due to variation, which gives them a survival advantage
a disease is less likely to affect all the individuals in a population
In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.
The advantages of asexual reproduction include:
the population can increase rapidly when the conditions are favourable
only one parent is needed
it is more time and energy efficient as you don't need a mate
it is faster than sexual reproduction
The disadvantages of sexual reproduction:
time and energy are needed to find a mate
it is not possible for an isolated individual to reproduce
The disadvantages of asexual reproduction include:
it does not lead to genetic variation in a population
the species may only be suited to one habitat
disease may affect all the individuals in a population

Sunlight is important in my life because you need it if you have a plant and you want to take care of the plant.Postive effects of sunlight is Sun water and needing health
Answer:
I know one reason is that plants need sunlight, and without plants we would all die. This is because plants need sun, and if we didn't have plants, we would be robbed of that resource, and then animals who eat the plants would die, so meat would be taken from us as well and we would all DIE.

White stars
Yellow stars
Blue stars
Red stars
Answer:
Blue Stars
Explanation:
Hope this helps :)
Blue stars tend to have higher absolute brightness for stars in the main sequence.
What is absolute brightness?Absolute brightness, also known as absolute magnitude, is a measure of the luminosity of a celestial object such as a star or planet, expressed as an apparent magnitude that the object would have if it were placed at a standard distance of 10 parsecs (32.6 light-years) away from Earth.
It is an objective measure of an object's intrinsic brightness, independent of its distance from Earth. Absolute brightness is a useful tool in astrophysics for comparing the luminosities of stars and determining the distance to remote stars and galaxies. It provides a standardized method of comparison, allowing scientists to study the evolution and distribution of stars and galaxies throughout the universe.

Climax community- most stable community that takes hundreds of years to develop. The types of organisms change due to __?__.
competition
random chance
being the luckiest
Answer:
competition
Explanation:
An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).
A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.
Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.

10. Wei saw a special type of plastic that would melt and become a liquid when it was placed in the sun, but it would not melt when placed under a desk lamp. Why does light from the sun melt the plastic when light from the desk lamp does not? Because the plastic can take in energy from the light from the sun but not from the light from the lamp. b Because light from the sun carries heat molecules, and light from the desk lamp does not. Because light from the sun pulls energy out of the plastic, and light from the desk lamp does not. Because the sun gives off a type of light that carries erlergy, and light from the desk lamp does not.
