Answer:
The inherited characteristics within a population change over time.
Explanation:
The evolution is related to the changes in the inherited characteristics over time in the biological population with the successive generation. These are inherited characteristics that are based on genes and passed from generation to generation through the process of offspring during reproduction.
Evolution can occur when the natural selection and the genes drift act together at the same level. The result is that some characteristics in the generation are common and some characteristics are different in this new generation.
Answer:Option C
Explanation:
Evolution can be defined as the change in the inheritable traits over successive generations.
The most preferable characters are selected by natural selection over a period of time. The organism having the desired trait will have more chances of survival as compared to the organism having no variation.
The characters that is inherited in the population changes over time is carried to the offspring.
Hence, the correct answer of this question will be option C.

How does DNA homology measure genetic relatedness ?
Answer:
by the nitrocellulose membrane filter method. (more info below)
Explanation:
Genetic relationship between mycoplasma as determined by nucleic acid homology. DNA from each of the mycoplasma isolates tested was reacted separately by complementary RNA synthesized with homologous or heterologous DNA as a primer. The amount of DNA-RNA hybrids formed was tested using the method of the nitrocellulose membrane filter.

The leeward side of a mountain receives far less rainfall than the windward side is what?
Much of airborne moisture falls as rain on the windward side of mountains. This often means that the land on the other side of the mountain (the leeward side) gets far less rain—an effect called a "rain shadow"--which often produces a desert.

Igneous rocks has been called the magmatic, are all rocks that are formed by the solidification of magma. However, igneous rocks are classified into two groups. First are the plutonic or intrusive igneous rocks that are the result of the solidification of magma within the lithosphere. Secondly, there are the volcanic or extrusive igneous rocks that are the result of the cooling of magma that occurs at the surface or a shallow depth.
Therefore, Sedimentary rocks leads to the transformation of igneous rock into sedimentary rock by moving it has been exposing it to energy from sediments as uplift, upward, the Sun and subduction, downward, Earth's Interior.

Which best describes Earth's south magnetic pole?
D - Moving
The south magnetic pole is the point on Earth's Southern Hemisphere where the geomagnetic field lines are directed vertically upwards. The Geomagnetic South Pole, a related point, is the south pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's actual magnetic field.

Alcoholic fermentation
1. Forms fewer ATP molecules and cellular respiration
2. Uses oxygen and ATP molecules as reactants
3. occurs in the muscle cells of animals and humans
Answer:
A.
Explanation:
It converts sugars into cellular energy without requiring much oxygen, but it doesn't provide nearly as much energy as a result of the process not using oxygen.
Answer:
1. Forms fewer ATP molecules and cellular respiration
Explanation:
Alcohol fermentation is usually done by yeast as us humans lack the genetic information to do it (however we can do lactic acid fermentation in low Oxygen level which produce Lactic acid, which is what hurts after a day or two of heavy playing or workout)
Alcohol Fermentation only produces two ATP which is significantly lower than what cellular respiration makes (scientists predict there to be about 38 ATP from per cycle of respiration)
How much sperm does a man produce each day
Answer:
about 525 billion sperm cells
Explanation:
In fact, the average male will produce roughly 525 billion sperm cells over a lifetime and shed at least one billion of them per month. A healthy adult male can release between 40 million and 1.2 billion sperm cells in a single ejaculation.
Answer:
1,500
uring spermatogenesis, your testicles make several million sperm per day — about 1,500 per second. By the end of a full sperm production cycle, you can regenerate up to 8 billion sperm. This may seem like overkill, but you release anywhere from 20 to 300 million sperm cells in a single milliliter of semen.

D. The endocrine system responds to a stimulus, and the nervous
system returns the body to a relaxed state.
Answer: option B.
The nervous system signals the endocrine system to release
hormones in response to a stimulus.
Explanation:
The nervous system respond to stimulus through action potentials and neurotransmitters and they signals the endocrine system to secrete hormones.
The endocrine system is responsible for secreting hormones into the blood which is transported to the target cells. These hormones are responsible for metabolism , growth and response to stress. The hormones secreted provide feedback to the brain so as to affect neural processing.

Explanation:
Coral reefs are both found in the littoral zone which is on the shore in a tidepool and in the benthic zone which is the low level of the ocean.
The aquatic ecosystems that is likely to have both a littoral and benthic zone is lake. The correct option is a.
What is littoral and benthic zone?The benthic zone, like the ocean, is the lake floor, made up of accumulated sunken organic matter.
The littoral zone is the area adjacent to the shore where light can easily penetrate and aquatic plants thrive. The pelagic zone encompasses a large body of water.
The Benthic Zone consists of organic sediments and soil at the bottom of a pond or lake. This zone will expand as the body of water ages. It is regarded as the digestive system of a pond or lake.
The littoral zone is a pond or lake's down-sloping shelf. This is the area that extends from the high-water mark to the shore and into the area where sunlight penetrates to the sediments at the bottom of a body of water.

B.
Pesticides from the farm wash off into the lake, causing algae to die and producing a green slime.
C.
D.
E.
Plants growing in the farm increase the chlorophyll levels in the ground, which runs off into the lake, causing the green slime.
The plants in the farm deplete the lake of nutrients and kill off microscopic organisms, causing the green slime.
The green slime in the lake is a toxin produced by pesticides that run off into the lake.

Answer:
A.
Nutrients from fertilizers on the farm wash off into the lake and cause the green slimy algal bloom
Explanation:
This question describes a team of marine biologists, who observe an inland sea covered up with a green slime. Firstly, this green slime is the the visible form of the proliferated growth of algae, hence, causing what is referred to as ALGAL BLOOM.
Algal bloom is caused by EUTROPHICATION, which is the pollution of water bodies with nutrients from fertilizers e.g phosphate, nitrate etc which causes a rapid algae growth. The excessive nutrients causing this algal bloom appearing like a green slime comes from the fertilizers used by farmers practising large scale farming within that area.
When this fertilizer is applied on plants, it gets washed into the water body and its constituents e.g phosphorus, nitrogen etc. serves as source of nutrient for the growth of marine organisms (algae). Hence, they grow excessively and form a bloom that appears like a green slime on the lake.
Hence, the farming activities is releasing pollutants in form of chemical substances which serve as nutrients for the proliferated growth of algae.
Answer:
B. Pesticides from the farm wash off into the lake, causing algae to die
Explanation:
Green slime algae is a type of algae which is found in the marine ecosystem. This algae is a source of food for aquatic animals. It requires nutrients for producing food in the process of photosynthesis. When the nutrients present in the fertilizers such as nitrates move from the farm into the nearby lakes, its population increases and more food is available for the marine animals and fishing is not possible. But this decrease occurs in population when the pesticides wash off into the lake so farming will be possible for the fisheries.
