Acceleration
Answer:
Newton's first law
Explanation:
The focus of Lesson 1 is Newton's first law of motion - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

matter and energy move through ecosystems between different organisms. how does matter travel through an ecosystem and through earths spheres?
Answer: In ecosystems, matter and energy are transferred from one form to another. Matter refers to all of the living and nonliving things in that environment. Nutrients and living matter are passed from producers to consumers, then broken down by decomposers. Decomposers break down dead plant and animal matter.

Why are normally unseen members of the food web, such as soil microorganisms, essential to the nitrogen cycle?
Answer: Why are normally unseen members of the food web, such as soil microorganisms, essential to the nitrogen cycle? ... Since not all organisms can utilize the nitrogen gas directly, these microorganisms convert nitrogen in different nitrogen compounds, such as ammonia, nitrites, and nitrates. In this article we explore how nitrogen is cycled and the important role of microbes in this cycle. ... Nitrogen is required by all living organisms for the synthesis of organic molecules such as amino acids, nucleic acids and proteins. The Earth's atmosphere contains almost 80% nitrogen gas
Bacteria play a central role:
Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates.
Bacteria of decay, which convert decaying nitrogen waste to ammonia.
Nitrifying bacteria, which convert ammonia to nitrates/nitrites.
Denitrifying bacteria, which convert nitrates to nitrogen gas.

Describe the connection between limiting factors and invasive spicies
Answer: factors that limit a population size are limiting factors. Biotic potential is the amount of organisms that could be supported in an ecosystem if plenty of resources were available. Factors that cause a population to increase are 1)births: the number of births in a population in a certain period of time. 2) immigration: when organisms move INTO a population.
Explanation:
some examples of limiting factors are natural hazards, amount of food, amount/quality of water and air, predators deforestation.
Your teacher gives you a task in science class. You must decide which of the five samples you are given are alive or were once alive. One specimen is a crust gray-green object. What is the BEST clue you could use to decide: living thing or not a living thing.
A) Does it move?
B) Does it have DNA?
C) Is it made of cells?
D) Can it make its own food?
The best clue that can be used to decide living thing or not a living thing is the observation of living or dead cells present in the specimen. All the living or dead organisms exhibit cells. Cell is a structural and functional unit of life. The growth and metabolism of living organism are dependent upon a cell. A cell in a life form exhibit organelles and components which are not found in non-living objects
The BEST clue you could use to decide: living thing or not a living thing- is option C. is it made of cells and
The living things have some basic characteristic features of life in them that help in determining if an object or thing is living or nonliving thing. these characteristic can be present in all or some, are as follows:
Cellular organization - made of cell is very basic trait of life of every living being.the ability to reproduce - it is present in almost every living thing it could be sexual or asexual.growth & development - living things grow and developenergy use - use energy to perform various functionshomeostasis - regulate according the environmentGenetic material : it can have DNA as genetic materialthus, there is two options only that present in every living organism that are made of cells and presence of DNA, but for DNA one need to investigate thoroughly so the correct answer is - C) Is it made of cells?

Number 8. was colorblind just like his father: Where did the son at 8 get his allele for colorblindness?
Answer:
son 8 inherited it from her.
Explanation:
Given that Son 8's mother is a carrier of the blindness allele
Assuming that the father is colorblind due to a genetic mutation, there are a few possible scenarios for how the son inherited the allele for colorblindness.
What is genetic inheritance?Genetic inheritance is the study of how certain inherited traits are passed down from generation to generation.
Assuming the father is colorblind due to a genetic mutation, there are a few possibilities for how the son inherited the colorblind allele:
His father's colorblindness allele was passed down to his son. The son in this case inherited the mutation from his father.The mother carries the colorblindness allele, which she passed on to her son. In this case, the son inherited the mutation from his mother, who is not colorblind but carries the gene.The colorblindness mutation is present in both the mother and father, and the son received one copy from each parent. This is a less likely scenario, but it is possible if both parents carry the gene.Thus, in any of these scenarios, the son inherited the allele for colorblindness from one or both of his parents.

What can you conclude about starch, glucose and their movement across the Visking tubing? , What implications does this have for starch and glucose in the small intenstine?
Answer:
Starch molecules is too large therefore cannot pass through pores of visking tubing, glucose molecules is small enough to pass through pores of visking tubing. Visking tubing is like small intestine in this experiment, where starch is too large to be absorbed through small intestine into bloodstream, glucose is small enough to diffuse through small intestine and to be reabsorbed into bloodstream.

What enzyme is used to break down bacteria
During glycolysis, the molecule glucose is broken down into pyruvate. What type of reaction is this?
Explanation:
Glycolysis is a set of anaerobic reactions, ones that does not need oxygen to be performed. It takes glucose and breaks it down into pyruvate. This has the result of creating two ATP, which can release energy.
Overall, this process creates four ATP, but it uses two ATP early in the reaction. This means that there is a net gain of two ATP.
The overall equation for this pathway is:
1 glucose + 2 ATP ⟶ 2 pyruvate + 2 NADH + 4 ATP + 2 H2O

In the oceans on either side of the Isthmus of Panama are 30 species of snapping shrimp, 15 species on the Pacific side and 15 different species ch the Atlantic sid. See different water depths. Morphological and genetic data show that Atlantic and Pacific species that live at similar depths are sister species. Geological evidence indicates that the Isthmus of Panama started rising about 10 million years ago and the oceans were completely separated by the stimus about 3 million years ago. If the geological evidence has been misinterpreted and the isthmus had formed very rapidly in less than 1,000 years), which of the following predictions is most likely?
A. greater percentage of difference in DNA sequences between sister species that inhabit deep water than between sister species that inhabt stalow water
B. greater percentage of difference in DNA sequences between sister species that inhabit shallow water than between sister species that inhabit deep water
C. similar percentages of difference in DNA sequences between all pairs of sister species
D. greater percentage of difference in DNA sequences between Atlantic species than between Pacific species
Answer:
The answer is "Choice A".
Explanation:
The Panama isthmus is indeed a patch of land which separates its sea from its Atlantic ocean to The pacific in two halves. The Panama Isthmus allows spreading the seafood applicable state, although due to geographical barrier, the very same turtle species were isolated. Its deep squirrels of liquid are diverged quite early as being against shallow water shrimps which are characterized by the rising of the Jamaica isthmus, first off the island can be crossed until it was closed through shallow water prawns and shallow-water animals. If Panama's black sea was established less than 1000 years, it has a greater effect on deepwater shrimp and very low water lobsters. Consequently, in water depth prawns, a disparity in hereditary degree (DNA) is higher than in shallow species. The deep waters have been affected earlier so the variation in DNA sequences throughout all sister species will not be the same.

Answer: The correct answer is a dog lying among the crops
Explanation: This answer has been confirmed correct.
A dog is a pet and is not causing damage to the crops. The other three options are all harming the plants (chewing, eating, and digging tunnels).
