(b) Many insects use litter on the soil surface as a habitat and for nutrients. Discuss how the invasion of earthworms is likely to change the forest food web. (2 points)

Answers

Answer 1

Earthworms are part of a special group of species that eat dead or decaying organic matter called decomposers. Earthworms are very important in the forest food web because they recycle the energy, and help us to start all over again.

What are earthworms?

An earthworm is described as a terrestrial invertebrate that belongs to the phylum Annelida exhibiting a tube-within-a-tube body plan; they are externally segmented with corresponding internal segmentation; and they usually have setae on all segments.

The invasion of earthworms burrowing activities mix the soil and improve the flow of air and water through the underground world. By eating dead organic material from the soil surface, dragging it down into the soil, digesting it, and then leaving their droppings, they redistribute nutrients throughout the soil.

In corgis, a breed of dog, short tails are completely dominant to long tails. If two long-tailed corgis have puppies, what is the percent chance of having a puppy with a short tail?

Answers

Answer:

0%

Explanation:

This question involves a single gene coding for tail length in a breed of dog called Corgis. The allele for short tail (S) is dominant over the allele for long tail (s).

According to this question, two long-tailed corgis are crossed i.e. ss × ss. Each parent corgis will produce only 's' gametes. Using this gametes in a punnet square (see attached image), the following proportion of puppies will be produced:

All ss (long-tailed) offsprings/puppies.

Based on the question asked, 0% or none of the puppies produced will have a short tail.

Explain how the nervous and endocrine systems work together to control the body and maintain homeostasis in a paragraph.

Answers

Answer:

Explanation:

The nervous system controls virtually all body activities, and the endocrine system secretes hormones that regulate these activities. Functioning together, the organ systems supply body cells with all the substances they need and eliminate their wastes. The glands of the endocrine system secrete hormones into the bloodstream to maintain homeostasis and regulate metabolism. The hypothalamus and the pituitary gland are the command and control centers, directing hormones to other glands and throughout the body.

Write a paragraph explaining the steps involved in a muscle contraction starting from the brain sending a signal to the muscle and ending with the muscle contraction.

Answers

Answer:

A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles.Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron. The neuromuscular junction is the name of the place where the motor neuron reaches a muscle cell. Skeletal muscle tissue is composed of cells called muscle fibers. When the nervous system signal reaches the neuromuscular junction a chemical message is released by the motor neuron. The chemical message, a neurotransmitter called acetylcholine, binds to receptors on the outside of the muscle fiber. That starts a chemical reaction within the muscle.Acetylcholine Is Released and Binds to Receptors on the Muscle Membrane.

A multistep molecular process within the muscle fiber begins when acetylcholine binds to receptors on the muscle fiber membrane. The proteins inside muscle fibers are organized into long chains that can interact with each other, reorganizing to shorten and relax. When acetylcholine reaches receptors on the membranes of muscle fibers, membrane channels open and the process that contracts a relaxed muscle fibers begins:

Open channels allow an influx of sodium ions into the cytoplasm of the muscle fiber.

The sodium influx also sends a message within the muscle fiber to trigger the release of stored calcium ions.

The calcium ions diffuse into the muscle fiber.

The relationship between the chains of proteins within the muscle cells changes, leading to the contraction.

Water or air

Answers

Answer:

Air

Explanation:

Air.

Why? Because air has a much lower specific heat capacity (Heat capacity - Wikipedia) per unit mass than water. Also, air is dispersed as a gas so that in any given volume the mass of air that would fill it is only a fraction of the mass of water that would fill the same volume. Take these two factors into consideration and you see that the amount of energy it takes to raise the temperature of a volume of air by one degree is minuscule compared to the amount of energy it takes to heat the same volume of water by one degree.

The one thing that is more challenging about air is actually getting the energy into it. Water is densely packed, whereas air molecules are much more widely separated, so that presents a heat conductivity challenge. However, if we’re talking about equipment specialized for heating air (i.e. a fan forcing air over heated coils) versus equipment specialized for heating water (flat plate, coils, pumps or no pumps, whatever), energy added at the same rate to each will heat an equivalent volume of air to a greater extent (i.e. raising temperature more quickly) that it will water.

Explanation:

A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.

Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes.

An eye can be defined as a specialized organ of sight with the capability to receive visual images that are subsequently transduced into neural signals and relayed to the brain for processing and interpretation. Some of the components of the human eye matched with their description are;

1. Aqueous humor: a transparent liquid which is located between the cornea and iris.

2. Ciliary muscles: muscles attached to the lens to change its shape.

3. Cone: a photoreceptor cell which functions best in bright light. It detects color.

4. Cornea: the transparent portion of the sclera at the front of the eye.

5. Iris: a special part of the choroid layer composed of colorful tissue.

6. Optic nerve: the nerve connecting the eye to the brain.

7. Photoreceptor: specialized cells located in the retina that receive light images.

8. Retina: a delicate light-sensitive membrane covering the inside of the eyeball.

9. Rod: a photoreceptor cell which is sensitive to dim light, but detects no color.

10. Sclera: a fibrous material surrounding the eye to give it shape.

11. Vitreous humor: a transparent jellylike substance filling the eyeball.

Answer:

1. A transparent liquid which is located between the cornea and iris - aqueous humor

2. Muscles attached to the lens to change its shape - ciliary muscles

3. A photoreceptor cell which functions best in bright light, it detects color - cone

I think ATP would be the answer in this instance. See, ATP is the pure form of energy that cells prefer to use. Sugars and fats are good for energy, too - but sugars and fats must be converted into energy before use. So ATP is the only energy source listed that doesn't need to be metabolized before the cell can use the energy.

animal has a behavioral adaptation, and how does it give the animal an advantage?
Animal Adaptation
Duck Webbed feet
Squirrel Collects and stores food
The duck, because the behavioral adaptation allows it to catch prey.
The duck, because the behavioral adaptation helps it survive the environment.
The squirrel, because the behavioral adaptation provides food during winter.
The squirrel, because the behavioral adaptation to have more offspring.

Answers

Answer:

B

Explanation:

Ducks have the webbed feet so, they could swim in the water so they don't drown. That is animal adaptation to the environment.

Based on the given table, the animal with a behavioral adaptation is the squirrel, which collects and stores food. This adaptation gives the squirrel an advantage by helping it survive during times when food is scarce, such as during the winter months, which is in the third option.

What is behavioral adaptation?

The behavioral adaptation of collecting and storing food is an important survival strategy for many animals, including squirrels. During times of abundance, such as the fall months, squirrels will collect and store food, such as nuts and seeds, in order to have a food source during times of scarcity, such as the winter months. This allows the squirrel to survive and avoid starvation during times when food is less readily available.

Hence, Based on the given table, the animal with a behavioral adaptation is the squirrel, which collects and stores food. This adaptation gives the squirrel an advantage by helping it survive during times when food is scarce, such as during the winter months, which is in the third option.

The protease inhibitors block the uncoating process of the human immunodeficiency virus by binding to protease. c. The protease inhibitors block the nucleic acid synthesis of the human immunodeficiency virus. d. The protease inhibitors inhibit the late protein synthesis and processing of the human immunodeficiency virus.

Answers

Answer:

d. The protease inhibitors inhibit the late protein synthesis and processing of the human immunodeficiency virus.

Explanation:

Protease inhibitors are antiviral agents used to fight against pathogenic viruses such as retroviruses (e.g., human immunodeficiency virus, HIV) and RNA viruses (e.g., hepatitis C virus). Protease inhibitors can drastically reduce the viral load. Protease inhibitors may target 1-virus-encoded proteases which are responsible to produce functional proteins from polyprotein precursors and 2-processing structural proteins that are required for virus assembly. Some examples of protease inhibitors include, among others, ritonavir and indinavir, which are used in patients with HIV infection.
