please mark as brainliest pleaseNO LINKS AND NO FAKE ANSWERS. Rather than push a heavy box from one room to another, a worker chooses to place the box on a wheeled cart. In terms of friction, explain why moving the box on the wheeled cart is easier than pushing.
Answer:
The reason why that pushing something on a cart is easier than pushing it around without a cart is very simple actually. Pushing something on a cart is much easier because there is a much smaller act of friction. This results in a smaller strain on the body.
Explanation:
There isn't really a need for an explanation because it's that simple. I don't blame you for not knowing it though. People don't know everything.

Explain why most humans require a supply of glucose.
Answer:
Nerve cells and chemical messengers there need it to help them process information so basically without it your brain wouldn't be able to work well
Explanation:
Most humans require a supply of glucose because Nerve cells and chemical messengers they need it to help them process information. Without it, your brain wouldn't be able to work well.
Why do we need glucose everyday?
Glucose provides energy for physiological processes such as respiration, heart rhythm and the regulation of body temperature.
Why is glucose required in the cell?
Glucose provides quick energy for cells. Fat has more energy than glucose, but it requires some chemical conversions before we can get it into the process of cellular respiration, so it takes longer to use.

Blood passes from the right ventricle to the _____ and then the _____ before reaching the lungs to pick up oxygen. Multiple choice question.
Blood passes from the right ventricle to the Pulmonary valve and then the Pulmonary artery before reaching the lungs to pick up oxygen
Blood circulation procedureWhen the blood enters the right ventricle it contracts and sends the blood through the Pulmonary valve before it reaches the Pulmonary artery which is passes the blood to the Lungs where it becomes oxygenated.
Hence we can conclude that Blood passes from the right ventricle to the Pulmonary valve and then the Pulmonary artery before reaching the lungs to pick up oxygen.

RNA is made because DNA is always in the nucleus,but ribosomes for making proteins are found in the _______
Answer:
Cytoplasm
Explanation:
In eukaryotes, there is a definite nucleus where the ribosome and mRNA production takes place. The ribosomes and mRNA come out of the nucleus into the cytoplasm where the ribosomes work upon and catalyze the formation of proteins. Meaning that in eukaryotic cell, ribosomes make proteins in the cytoplasm.
Explanation:
Ribosome existed in the rough endoplasmic reticulum and existed freely in cytoplasm
Consider three independently assorting gene pairs, A/a, B/b, and C/c, where each demonstrates a typical dominance (A-, B-, C-) and recessiveness (aa, bb, cc) relationship. What is the probability of obtaining an offspring that is triply dominant from parents that are AaBbcc and AaBbCc
Assuming complete dominance and following the product probability rule, the probability of obtaining an offspring that is triply dominant AABBCC is 1/32.
What is complete dominance?
We talk about complete dominance when the dominant allele completely masks the recessive allele. It is an inheritance pattern.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant phenotype. The dominant allele is hiding the expression of the recessive allele.
Many genes show complete dominance.
In the exposed example, we need to cross AaBbcc x AaBbCc and calculate the probability of getting offspring that is triply dominant. To do it, we will follow the product probability rule.
What is the product probability rule?The product probability rule allows us to calculate the probability of occurrence of event A and event B at the same time.
It is about a joint probability of two or more events that might happen simultaneously, not excluding each other.
This rule is based on the dependence or independence of the events. If two events A and B are independent of each other, the occurrence of one of them does not affect the occurrence of the other one.
For independent events, the rule establishes that, given two different events A and B, the probability of occurrence of both together is
P(A∩B) = P(A) x P(B)
Since these are independent genes, for easier calculations, we can perform crosses that involve each of the genes separately -events-, and then multiply de results according to the genotype we are interested in (AABBCC).
Gene A
Parentals) Aa x Aa
Gametes) A a A a
Punnett square) A a
A AA Aa
a Aa aa
F1) 1/4 AA
1/2 Aa
1/4 aa
Gene B
Parentals) Bb x Bb
Gametes) B b B b
Punnett square) B b
B BB Bb
b Bb bb
F1) 1/4 BB

1/4 bb
Gene C
Parentals) cc x Cc
Gametes) c c C c
Punnett square) C c
c Cc cc
c Cc cc
F1) 1/2 Cc
1/2 cc
The probability of getting and individual with genotype AABBCC is
P(AABBCC) = P(AA) x P(BB) x P(CC)
P(AABBCC) = 1/4 x 1/4 x 1/2
P(AABBCC) = 1/4 x 1/4 x 1/2
P(AABBCC) = 1/32
The probability of obtaining an offspring that is triply dominant AABBCC is 1/32.

What is succession?It is the gradual change to the community of plants and animals in an ecosystem until a stable community is reached.
Succession can be primary or secondary. Primary succession happens on newly colonized bare grounds of stones while secondary succession happens in an existing community after a period of disturbance such as wildfire.
A forest ravaged by fire will have all the animals dead or away for safety reasons. These animals may not come back until regrowth has reached a certain level.
However, propagules of grasses are often fire-resistant and even get stimulated by fire in most cases. Thus, the first type of organism to be found living in the burned area could be grasses.

When a group of proteins such as interferons and interleukins are released by the t cells, intercellular signals begin the immune response, what is the medical term used for the group of proteins?.
The cytokine describes the group of proteins such as interferons and interleukins that regulate cell communication, mainly produced by the immune system in normal and pathological conditions.
What is a cytokine?They are messenger molecules with a glycoprotein structure, whose lifetime is short and generally secreted in cascades.
They are produced by different activated cells, responsible for innate and/or acquired immunity, and regulate the immune and inflammatory response.
Therefore, we can conclude that the cytokine describes the group of proteins that regulate cell communication, mainly produced by the immune system in normal and pathological conditions.

Answer:
The common things between all species are DNA, RNA, amino acids, and ATP. All living things have the same biochemical building blocks.
It shwos that although we all have similar structures and make-up, who we evolved from counts for who we are. Species come from the same things but differenciate over time due to evolution.
I think that a horse and a donkey would have the fewest differences. I think this because the two species are very similar and amino acids refect the similarities between two species. Both horses and donkeys have a similar structure and make-up, which is determine by amino acid sequences.

Summarize the weather and ecological conditions associated with each season?
Answer: Seasons have an enormous influence on vegetation and plant growth. Winter typically has cold weather, little daylight, and limited plant growth. In spring, plants sprout, tree leaves unfurl, and flowers blossom. Summer is the warmest time of the year and has the most daylight, so plants grow quickly. In autumn, temperatures drop, and many trees lose their leaves.
