Explanation:

Compare the exoskeletons of two invertebrates: a grasshopper (Arthropod) and a clam (Mollusca). How do they differ in relation to support and movement?

Answers

Answer:

Mollusca: Unsegmented exoskeleton, with no appendixes articulated to them. This skeleton has a calcareous origin. Arthropoda: Segmented exoskeleton, with different appendixes articulated to them, which develop different functions. This skeleton has a chitinous origin.

Explanation:

Clams are bivalves. Their calcareous exoskeleton has two valves dorsally articulated to each other. They do not articulate with any appendix, although. These animals also have a foot, a small head, and a developed mantle cavity. The valves are convex, oval, and unsegmented. They are composed of three layers: periostracum, prismatic, and pearly. En the dorsal portion of each valve, there is a bulge called the umbo, which is the oldest part of the valve. The articulation has some teeth-shaped structures that are intercalated, maintaining the valves together and fixed. Grasshoppers have a chitinous exoskeleton divided into three principal segments or regions that allow their movement: head, thorax, and abdomen. The head is orientated in such a manner that their feeding apparatus is heading down. Also, the head segment has composed eyes and antennae. The thorax is the medial region of the body. It has three segments: the prothorax, mesothorax, and metathorax. Each of these segments articulates with a pair of legs. Finally, the abdomen is composed of many segments that might reach up to 7 or 11.

What methods would the body use to provide a
person with energy throughout a race?
DONE
C
Intro

Answers

Answer:

The methods the body would use to provide a person with energy throughout a race is using the ATP in the muscle cells for the first 3 seconds.

For the next 8 to 10 seconds, the body replaces the used ATP and produces more.

Within the next 90 seconds of the race, anaerobic respiration is used up to make more ATP (Adenosine triphosphate).

Therefore, during the whole process, the three energy systems used are:

the ATP-PC System

the Glycolytic system

the Oxidative system

Motor neurons play a role in movement, including voluntary and involuntary movements. These neurons allow the brain and spinal cord to communicate with muscles, organs, and glands all over the body.

Interneurons

Interneurons are neural intermediaries found in your brain and spinal cord. They’re the most common type of neuron. They pass signals from sensory neurons and other interneurons to motor neurons and other interneurons. Often, they form complex circuits that help you to react to external stimuli.

If there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons, how much will the action potential rate increase if the stimulus intensity increases by 100?

Answers

Answer:

The action potential rate will be doubled

Explanation:

The logarithm of a number for a given base is the power to which the base must be raised to give the number. Logarithm of a number can be in different bases. The base of common logarithm is the base 10.

For example, logarithm of 1000 to base 10 is 3 because 10 raised to power 3 equals 1000

Log₁₀1000 = 3 since 10³ = 1000

Therefore, if there is a logarithmic relationship between stimulus intensity and action potential frequency in sensory neurons and the stimulus intensity increases by 100, the action potential rate will increase thus:

Log₁₀100 = 2

Therefore, the action potential rate will be doubled

If a cell in G1 has 20 chromosomes, then at the end of meiosis I there will be _________ chromosomes in each daughter cell, and __________ sister chromatids in each daughter cell.

Answers

Answer:

10 chromosomes

20 chromatids

Explanation:

Meiosis is the process by which sexually reproducing organisms produce gametes for sexual reproduction. Meiosis, which reduces the chromosomal number of the parent cell by half, occurs in two stages namely: meiosis I and meiosis II.

Meiosis I is where the actual reduction in chromosomal number takes place because homologous chromosomes are separated in this stage. For example, a cell in G1 that has 20 chromosomes will have 10 chromosomes in each daughter cell at the end of meiosis I.

Since, DNA replication occurs in the S-phase, sister chromatids are formed for each chromosome. Hence, there would be 20 sister chromatids joined together by a centromere at the end of meiosis I.

The commercial fishing industry uses large nets to capture fish. Often these nets catch many species of organism that are not used by humans. What Change could lessen the negative effect to this practice for the commercial fishing industry?


A. Designing nets that release unwanted species without harming them.

B. Using the net in deeper regions of the ocean where different organisms live.

C. Decreasing the size of the nets, but using more of them.

D. Exploring new and uncharted areas of the ocean where the nets can be used.

Answers

Answer:

A. Designing nets that release unwanted species without harming them.

Explanation:

Over-fishing is a negative human practice that leads to the over-exploitation of aquatic ecosystems (i.e., both marine ecosystems and freshwater ecosystems). In an aquatic ecosystem, the communities of organisms coexist in a delicate balance where they are dependent on each other in the food web, providing stability to the whole ecosystem. Therefore, the over-exploitation of any aquatic species is expected to impact the whole ecosystem, thereby also having a negative impact on other fish populations.

John predicted that the organic fertilizer would make the plants grow taller. He used three pots, three of the same type of seed, soil, organic fertilizer, chemical fertilizer, water, and a ruler. John put soil in the pots. He added chemical fertilizer to the first pot, organic fertilizer in the second pot, and no fertilizer in the third pot. He then planted one seed in each pot. John had to water the pots daily. He also checked for growth and took measurements for a period of 10 days. He measured the height of the plants.

This question is incomplete; the complete part is: what are the independent, dependent, and controlled variables?

Independent variable: ORGANIC AND CHEMICAL FERTILIZERS

Dependent variable: HEIGHT OF PLANT

Controlled variable: Same type of seed, water

Explanation:

Independent variable is the variable that is changed or manipulated by the experimenter. In this question, John wanted to test the effects that organic and chemical fertilizers had on plant growth. Hence, the independent variable is the ORGANIC AND CHEMICAL FERTILIZERS used.

Dependent variable is the variable that responds to changes made to the independent variable. The dependent variable is the variable that is measured in an experiment. In this case, the HEIGHT OF PLANTS MEASURED is the dependent variable.

Controlled variable or Constant is the variable that is kept unchanged throughout the experiment in order not to influence the experimental result or outcome. In this case, the controlled variable is the SAME TYPE OF SEED USED, WATER.

Independent Variable: organic + chemical fertilizers
Dependent Variable: height of the plants
Controlled Variable: seed, soil, water
