Explanation:
Differentiate between weather and climate
Answer:
The term "weather" means the state of the atmosphere in a shorter period of time, while the term "climate" refers to how the atmosphere behaves in the long run.
Explanation:
When we talk about climate change, we are talking about long-term change.
"tTme" describes the way in which the atmosphere "behaves", which primarily means the effects that this "behavior" has on life. The biggest difference between climate and weather is that the term "weather" refers to extremely short-term changes in the atmosphere - so short that they are measured in minutes and months.
Which layer of soil contains large rocks that have not been weathered yet?
A. Topsoil
B. Dirt
C. Bedrock
Answer: Option C.
Bedrock

Most igneous activity takes place?
Answer:
under the ground in volcanoes
Explanation:
There are some volcanically active spots that are in the middle of a tectonic plate.
The interior of the Earth is hot, while the surface or crust of the planet is cold. Between these layers are areas of molten rock. These molten rocks are less dense, so they easily break through cracks in the Earth's crust.
Magma is molten rock and is found beneath Korea. Beneath the volcano, in the underground spaces, magma accumulates.

In one or two sentences, explain how the chemical equation for cellular respiration shows that plants cycle matter. Include the numbers of molecules and atoms involved to support your explanation.
Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.
Glucose + Oxygen ------> ATP + Carbon dioxide + Water
C6H12O6 + 6O2 ----------> 36ATP + CO2 + H2O
The chemical equation for cellular respiration shows that plants cycle matter because oxygen and glucose that is produced by the plants is used by the human body for the generation of energy in the form of ATP molecules, water and carbondioxide gas.
This carbondioxide gas is released by animals which is used by the plants in order to make their own food during the process of photosynthesis so we can conclude that the chemical equation for cellular respiration shows that the plants cycle matter.

If a gene has two alleles, and allele A has a frequency of 83 percent, then allele a has a frequency of:_______
Answer:
Another allele frequency = 17%
Explanation:
Given:
Allele A has a frequency = 83 percent
Find:
Another allele frequency
Computation:
Sum of percent = 100%
So,
Another allele frequency = 100% - 83%
Another allele frequency = 17%

Answer:
limiting factors
Explanation:
The ecological optimum represents the value of the factors within the ecological valence at which the life processes of a species take place best. The upper and lower limits of an ecological valence are its maximum and minimum. Beyond these limits, physiological processes are interrupted and death occurs.

Is hemoglobin a hormone?
Answer:
I'm really sorry it is not.
A new hormone called erythroferrone, which regulates the iron supply needed for red blood-cell production, has been discovered by researchers. Iron is an essential functional component of hemoglobin.
Hemoglobin is the iron-containing protein compound within red blood cells that carries oxygen throughout the body. It is made up of heme, which is the iron-containing portion, and globin chains, which are proteins. The globin protein consists of chains of amino acids, the "building blocks" of proteins.

Answer:
Importance of building specie database, for restoration projects.
Explanation:
Restoration implies human intervention, for renewing - degraded ecosystems & habitats.
Building species data base is important for this, as - wildlife is an integral part of habitat. Understanding their favourable living ambience in ecosystem - like temperature, humidity, sunlight & water access and migration patterns is important - in effort to restore environment in real sense.
Sally is working on a farm and cuts her hand whilst opening a gate.
The cut becomes infected with bacteria that then invade the tissues of the finger.
The bacteria begin to multiply, each division doubling their number.
There are now too many bacteria for Sally’s immune system to cope with. The infection spreads.
Sally goes to the doctor to get some antibiotics. The doctor prescribes penicillin tablets and Sally begins to take the medicine. Many of the bacteria are killed by penicillin. Some bacteria however are naturally resistant to the antibiotic and so are not killed. These bacteria are said to be adapted to their environment.
The resistant individuals then multiply, increasing their numbers a million-fold in a day. Soon the antibiotic resistant bacteria become very common in the population. Sally’s infection is now very serious and will soon spread throughout her entire body. She returns to the doctor.
1. Does the antibiotic cause the resistance to the antibiotic?
2. In this example, how do you know that antibiotic resistance has a genetic basis?
3. What should the doctor now do to help Sally get better?
