1. Energy is often considered the “Fuel of Life”. Primarily, it is needed for maintaining basic
metabolism (maintenance energy). Any excess is then used for production of meat (growth)
and/or eggs (production). Fed too much energy, hens become overweight (excess growth)
leading to poor production. If fed too little energy, hens begin using protein to meet their basic
maintenance needs and egg production may be compromised. As is the case with most things
in life, balance is the key. This article is an attempt to provide a flock manager with some tools
to use when making decisions on feeding energy to a breeder flock. Some of the research
cited is not current and is in no way intended to be anything more than an example of the
thought processes that may be helpful when making difficult decisions about feeding.
Energy is essential to meet our most basic needs: cooking, boiling water, lighting and heating. It is also a prerequisite for good health – a reality that has been largely ignored by the world community.
2. Coal and diamond are two examples of carbon allotropes, where the carbon atoms are bonded together in different configurations. These structural differences result in very different material properties, such as hardness.
On its own, carbon cannot form diamonds under the surface of the Earth. Both coal and diamond are made primarily from carbon, but their chemical structures are significantly different. Coal is formed from highly impure carbon that often contains elements like oxygen, selenium, hydrogen, nitrogen and sulfur.

a population of white moths lives in a forest near a factory. this factory burns coal and pollutes the air with black dust. over time, this dust has settled on the trees in the area, making them darker in color. this could result in
1. an increase in the white moth population.
2. a decrease in the white moth population
3. an increase in the number of trees in the area
4. a decrease in the air pollution affecting the area
In roses, red flowers and long stems are dominant traits. A rose plant that is homozygous for both red flowers and long stems is
crossed with a rose plant that is heterozygous for red flowers and homozygous for short stems. What percentage of the offspring
will exhibit red, long-stemmed flowers?
25 percent
O 50 percent
O 75 percent
O 100 percent
Answer:
This is late but the answer is 100%
Explanation:
I got a 100 on the test
The percentage of the offspring that will exhibit red, long-stemmed flowers is 100 percent; that is the last option as all of the offspring will show dominant traits, which are red, long-stemmed.
What is genetic crossing?In the context of genetics, traits are characteristics that are passed down from parents to offspring through their genetic material (DNA). These traits are determined by genes, which are segments of DNA that contain the instructions for the development of a particular characteristic. Here, the gene for flower color in roses has two alleles: R (red) and r (white). The R allele is dominant, and the r allele is recessive. Similarly, the gene for stem length has two alleles: L (long) and l (short). The L allele is dominant, the l allele is recessive, and from the cross, all will be dominant.
Hence, the percentage of the offspring that will exhibit red, long-stemmed flowers is 100 percent; that is the last option.

Which type of selection leads to increased phenotypic and genetic variation? directional selection disruptive selection stabilizing selection species selection
Answer:
diruptive selection/ diversifying selection
Explanation:
disruptive selection often leads to more variations in species
The circumstance that concludes whether the organism will be able to accommodate and endure in the changed conditions is called selection.
The correct answer is:
Option B. Disruptive selection.
This can be explained by:
Disruptive or diversifying adaptation occurs when there is a change in population genetics in which the traits are valued over intermediates.This type of assortment supports either the dominant or the recessive trait but do not favour intermediates.For example, in selection between tall, short or intermediate organisms the tall and short will be selected over the medium heightened organism.Therefore, disruptive selection will lead to increased phenotypic and genetic variation.

The cause of humanity's increased water consumption is an increased population. What is the effect?
Option are not provided in the question. The complete question is as following:
The cause of humanity's increased water consumption is an increased population. What is the effect?
A. less potable water, a growing threat to biodiversity
B. more potable water, a growing threat to biodiversity
C. less potable water, a decreased threat to biodiversity
D. more potable water, a decreased threat to biodiversity
Answer:
A. less potable water, a growing threat to biodiversity
Explanation:
The increasing population of human causes increase in water consumption that leads to reduction in portable water, which is a growing threat to biodiversity .
Portable water or freshwater is used for drinking by humans beings along with that it provide habitat to many diverse marine wildlife and they are important to local ecosystems as they provide sources of income and food to humans and other wildlife.
Freshwater or portable water play very important role to control flood and erosion.
So, decrease in portable water result into decrease in biodiversity.
Hence, the correct option is A. less potable water, a growing threat to biodiversity .

For diffusion to occur, which condition must be met?
A concentration gradient must exist.
A hypotonic external environment must exist.
A hypertonic external environment must exist.
Dynamic equilibrium must exist.
Answer:
A concentration gradient must exist.
Explanation:
For diffusion to occur, a concentration gradient must exist. Therefore, the correct option is A.
The movement of molecules along a concentration gradient is known as diffusion. It is a significant process that all living things go through. Diffusion facilitates the flow of materials into and out of cells.
Without the use of energy, molecules can be transported from an area of high concentration to an area of low concentration through the process of diffusion. Simple diffusion and Complex diffusion are the two types of diffusion. Diffusion was made easier.

what causes ocean tides to reach higher up on a shore at certain of day than at others?
Answer:
Most tides are semidiurnal, which means they take place twice a day. For example, when an area covered by the ocean faces the moon, the moon's gravitational force on the water causes a high high tide. As the Earth rotates, that area moves away from the moon's influence and the tide ebbs.
Explanation:
Answer:
D. The moons gravity and Earth’s rotation
