Use the picture to explain how CONVECTION heat transfers could be responsible for the weather in our atmosphere.
Answer the question in 2-3 complete sentences.
Answer:
The sun's waves heat the ground, causing it to warm (radiation). The energy flows from the warmer ground to the cooler air (conduction), causing it to rise (convection). When the rising air reaches a certain point, it expands, cools, and the cooler expanded air can no longer hold as much water vapor so it rains.
Explanation:
When an organism joins a new population, its genes become part of the new population’s gene pool. How does this gene flow affect populations?
Gene flow between populations has no effect on the gene pool.
Gene flow between populations increases genetic diversity over time.
Gene flow between populations decreases genetic diversity over time.
Gene flow increases the chance for reproductive isolation which can cause new species to form.
Answer:
B . Gene flow between populations increases genetic diversity over time.
Explanation:
Gene flow affect populations when the Gene flow between populations increases genetic diversity over time ( option B )
The effect of gene flow is to reduce genetic differences between populations, thereby preventing or delaying the evolution of the populations in different geographical areas into separate species of the pathogen.
Gene flowGene flow is the movement of genes from one population to another population. It is the introduction of genetic material from one population of a species to another, thereby changing the composition of the gene pool of the receiving population.

How does a mouse reproduce ?
Answer:
Mice are breeding machines. They have a gestating period of 19 to 21 days. A female mouse gets pregnant about 5 to 10 times each year and can give birth to a litter of 3 to 15 pups. On average, a female mouse atleast give birth to 35 to 56 pups. The mice reproduce each year, and the mother can mate immediately after giving birth.

Carbon cycles through various reservoirs on Earth. The time it takes to form these reservoirs varies greatly. Which process in the carbon cycle takes millions of years to form the indicated reservoir?
A. release of carbon into the atmosphere while breathing
B. incorporation of carbon through digestion into animals tissues
C. breakdown of carbon in plant tissues
Breakdown of carbon in plant tissues to form fossil fuels (e.g., oil) takes millions of years to form reservoirs of Carbon (Option C). This element is present in all cells of an organism.
The carbon cycle is the process by which carbon atoms continually circulates between living things (biotic factors) and non-living things (abiotic factors)The carbon cycle consists of four different processes, i.e., photosynthesis, respiration, decomposition, and combustion.During the carbon cycle, the atoms of carbon move from fossil fuels (e.g., coal, oil) to the atmosphere when fuels suffer combustion (i.e., when they are burned).In conclusion, the breakdown of carbon in plant tissues to form fossil fuels (e.g., oil) takes millions of years to form reservoirs of Carbon (Option C). This element is present in all cells of an organism.

The text box shows observations made of an unknown organism. Based on this information, the organism most likely belongs to which kingdom? (SC.912. L.15.6)
UNKNOWN ORGANISM
.
.
.
Nucleus present
Mitochondria present
Cells grow in columns
Cell wall made of chitin
Decomposer
.
Animalia
Eubacteria
O Fungi
Plantae
Answer: C fungi
Explanation:
The unknown organism described in the text box has several key characteristics that can be used to identify which kingdom it belongs to. By examining the presence of a nucleus, mitochondria, and a cell wall made of chitin, one can make an educated guess as to which kingdom the organism belongs to.
What is the characteristic of an eukaryotic one ?The presence of a nucleus and mitochondria is a characteristic of eukaryotic cells, which indicates that the organism is likely not a prokaryote.
This rules out the Eubacteria kingdom, as prokaryotes are the only organisms that belong to this kingdom. Additionally, the presence of a cell wall made of chitin indicates that the organism is likely a fungus, as this is a common characteristic of fungi.
The fact that the cells grow in columns further supports the idea that the organism is a fungus, as this is a common growth pattern for fungi. The fact that the organism is a decomposer also supports the idea that it is a fungus.
Fungi are well known for their ability to break down organic matter, and as such, are often found in decomposer roles in ecosystems. This further supports the idea that the organism belongs to the Fungi kingdom.
In conclusion, based on the information provided, it is likely that the unknown organism belongs to the Fungi kingdom. The presence of a nucleus and mitochondria, the cell wall made of chitin, the growth pattern of the cells, and the fact that it is a decomposer all support this conclusion.

A diagram that shows the amount of energy that moves from one feeding level to another in a food web is
A: food chain
B: energy pyramid
C: ecosystem
D: niche
Energy plays a important role in the propagation of life in ecosystems. Food chain shows the amount of energy that moves from one feeding level to another in a food web. Thus, the correct option is A.
What is food chain?A food chain is defined as the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism.
The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain. A system of interlocking food chains is called a food web.

How does the operator region of DNA work to regulate gene expression?
Answer:
Explanation:
Operator region are region of DNA (deoxyribonucliec acid) that repressors protein binds to prevent transcription.
Repressor is an example of regulatory protein they regulate the rate at which transcription of operon occurs . A repressor functions when its bounded to the operator and it prevent enzyme RNA (ribonucliec acid)polymerase from moving to DNA to transcribe the nitrogenous bases by placing a complementary base pair.
Activators are other regulatory proteins that bounds to its DNA binding site and increases transcription of the operon.

PLEASE HELPPPPP!!!!! The law of conservation of mass states that the mass of all the substances present before a chemical change equals the mass of all the substances remaining after the change. Design an experiment to verify this law.
Answer:
Use the vingear and baking soda experiment but change it to lemon and not vingear.
Explanation:
A chemical reaction takes place when vinegar and baking soda are mixed. One of the new substances formed is carbon dioxide gas. If the carbon dioxide gas is contained, the mass of the substances will stay the same according to the Law of Conservation of Mass. If the gas is allowed to escape, the mass will be less
