Answers

Answer 1

Answer:n = 23,may there are 223, or about 8 million

Explanation:

possible chromosome combinations! The number of different chromosome combinations in gametes is one factor that contributes to genetic variation. A second factor is crossing over the exchange of genetic material between homologous chromosomes.

Answer:

3/8

Explanation:

I think I can help with completing the question.

Above each punnet square, the genotypes of the parents were given right? something like this:

Parent 1 fur genotype: Ff                             Parent 1 eye genotype: Ee

Parent 2 fur genotype: Ff                            Parent 2 eye genotype: ee

       F         f                                                              E        e

F     FF       Ff                                                    e     Ee      ee

f      Ff        ff                                                     e     Ee      ee

Probability of black fur if dominant is:               Probability of red eyes:

    3/4                                                                       2/4= 1/2

Probability of a trait combination such as black fur and red eyes is

3/4*1/2 = 3/8.

Explanation:

A substance valued or required by any living organism(s) for survival is defined as a resource.

What is living organism ?

The environment consist of both  living and nonliving organisms with two interacting components such as Physical or abiotic and biological or biotic components.

The physical component are  temperature, light, soil, air, and water where as the biological component are animals, plants, and microorganisms.

The biotic components are plants, animals, and micro-organisms while green leaves of the autotrophic plant have chlorophyll and this pigment help in making  food using light, water, and carbon dioxide by the process of photosynthesis.

Animals on the other hand are heterotrophs need nutrients and absorb nutrients such as nitrogen, phosphorus, and calcium from the soil.

Decomposer and Scavengers  feed on the dead bodies and decaying substances, animal release the nutrients trapped inside them.

Describe the various defense mechanisms your body has to fight pathogens, nonspecific and specific. How does not washing your hands properly affect these mechanisms?
DO NOT COPY AND PASTE I WILL CHECK AND YOUR ANSWER WILL BE DELETED :)

Answers

skin, tears, mucus, saliva, even urine can all wipe pathogens out of your body, although without proper hand washing/cleaning those mechanisms can become weaker and less able to fight pathogens. cleaning your hands is one of the best ways to prevent viruses, and flus, because the active germ killers in soaps and hand sanitizers will wipe the germs off of your body.

The human body has several defense systems to deal with both generalized and specific infections. Specific defenses are targeted responses that identify and eradicate particular diseases, while nonspecific defenses are general processes that protect the body against a variety of pathogens.

What are Specific and Non-specific defenses?

Physical barriers such as skin and mucous membranes, which prevent infection from entering the body, are examples of nonspecific defenses. Additional general protections include:

1. Inflammation:

A local response to injury or infection, known as inflammation, involves the mobilization of immune cells to the site of injury or infection to get rid of pathogens and encourage tissue healing.

2. Fever

Fever is an increase in body temperature that can aid in the fight against infection by slowing the growth of certain bacteria and increasing immune cell activity.

3. Phagocytosis

Pathogens are engulfed and destroyed by immune cells through a process called phagocytosis.

Specific pathogen exposure leads to specific immune responses known as specific defenses. These defenses require immune cells to recognize pathogens and mount a focused attack to destroy them. Special defenses include:

1. Production of Antibodies: Specialized immune cells make antibodies that can recognize and combat particular infections.

2. T cell activation is the process through which specialized immune cells known as T cells activate and kill cells that are infected with particular diseases.

3. Immune memory is the ability of the immune system to remember and respond more successfully to particular infections it has previously encountered.

When you don't wash your hands enough, you introduce viruses into your body and weaken both non-specific and specific defense mechanisms. For example, if you touch your face after touching a contaminated surface, you may introduce pathogens through your mouth, nose, or eyes, bypassing physical defenses against infection. By making the body's defenses less efficient and increasing the risk of infection, it can make it easier for microorganisms to cause disease.

Therefore, the human body has several defense systems to deal with both generalized and specific infections.

how does heat from the sun warm the earth?

Answers

Answer: the sun heats the earth through radiation

Explanation:

Answer:

Heat from the sun may warm the Earth when greenhouse gases absorb infrared radiation (IR), which you cannot see but can feel as heat. Dark surfaces also play a huge role in heating up Earth's surface, as they reflect less light and absorb most of the energy from the sun, in contrast to lighter surfaces, which reflect more light than it absorbs.

Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.


Answers

Answer:

conclusion

Explanation:

hope this helps

Answer:

1. What caused the tree bark to become darker than it was, was the soot from factories in the Industrial Revolution.

2. The light-colored peppered moths have a higher rate of survival on the light bark since it's the same color as it and can't be easily spotted.

3. The dark-colored peppered moths have a higher rate of survival on the dark bark since it's the same color as it and can't be easily spotted.

4. What caused the population of light-colored peppered moths to decrease was the color of the tree bark. The tree bark was dark from the soot from factories. If the tree bark was a dark color, then light-colored peppered moths are more easily spotted, and since the tree bark is a dark color the dark-colored peppered moths can hide more easily, and not be as spotted than the light-colored peppered moths.

5. You have to answer this question. If the tree bark is a dark color, then the dark-colored moths have a better chance of surviving, but if the tree bark is a light color, then the light-colored moths have a better chance of surviving.
