Explanation:
I hope its right :)
Answer:
The answer is D
Explanation:

What statement is not apart of the cell theory
Scientists are studying the mating habits of a population of butterfly fish on a Caribbean coral reef. They discover that both the largest and smallest males get the most mates and pass on the largest number of genes to the population's offspring. The largest males get a large number of mates because they can guard the females, preventing most of the smaller males from mating. However, the very smallest males also get a large number of mates because they escape the notice of the larger males and are able to mate with the females quickly. Based on these observations, which selective force appears to be acting on male body size in this population?
Answer:
The correct answer is - Disruptive selection.
Explanation:
Disruptive selection is a mode of natural selection that exhibits that two extreme values of phenotypic traits of the population are favored by this population than the population with their intermediate values. Disruptive selection occurs when there is a fitness advantage of extreme values of phenotypic traits over more intermediate phenotypes.
In this case, the largest males mates more, due to fact that they can guard the females, than smaller males. The smallest fishes also get a high number of mates as are able to mate with the females quickly without coming to the notice of larger males.

menstruation
it is the shedding of endometrium layer of uterus in females
it is a cycle of 28 days and menstruation occurs in first 5 days of cycle
if female is pregnant then there ia no menstruation
Answer:
mensturation
Explanation:
if the unfertilized egg pass out of the female body then mensturation occurs but if the egg fertilized with the men's sperm the fertilized egg travels through the fallopian tube to implant itself into the uterus.And finally women is considered pregnant.

Humanity faces a great number of environmental challenges, including: resource depletion, ecosystem service deterioration, pollution, biodiversity loss and climate change. Technology and research have both had positive and negative effects on the environment. Evaluate the impact of scientific research and technology on the environment. What are some ways that scientific research has harmed the environment. Choose ALL that apply. A) Research has led to the depletion of natural resources. Eliminate B) Air, water, heat and noise pollution can all be caused by producing and using technology. C) Scientific research has led to widespread increases in carbon emissions which has led to global climate change. D) Scientific research has caused widespread habitat disturbance and destruction as scientists have invaded ecosystems. E) Manufacturing technology creates large amounts of waste, and used computers and electronics get thrown out when they break or become outdated.
Answer:
Option B and E and D
Explanation:
Technological advancement has led to growth of industries and manufacturing units and hence the net production of goods. This has led to the use of natural resources and release of pollution of all forms. Environmental research leads to intrusion into niche habitats and hence causes its destruction.
Option B, D and E are correct

Do you think if the environmental conditions in an area changes that the plants and animals that inhabit that region will change their features to adapt to the changing conditions?
Answer:
yea
Explanation:
cause our climate conditions changes everyday depends on the atmosphere at that time so if there fire in a forest all the animals there have to adapt to the smoke.
Yes, if the environmental conditions in an area changes that the plants and animals that inhabit that region will change their features to adapt to the changing conditions.
Why plants and animals will change their features?
Plants and animals are fundamentally different in many ways, but one of the most obvious is in how they deal with temperature.The climatic niche of a species reflects where it can live.A species with a wide climatic niche can range widely across many different conditions and may be especially resilient to climate change.Different sets of plant and animal species tend to occur at different elevations, which differ in temperature and precipitation.

how is classification of animal related to its adaptational features
Answer:
it is important because it helps us identify and name all the animals on earth
Answer:
We can classify organisms on the basis of its physical features.
Explanation:
Classification of animal is related to its adaptational features because adaptational features of an organism provides information about the organism to which specific kingdom or phylum the organism belongs. These adaptational features are gained by the organisms due to different environmental as well as climatic conditions the organism have which make changes in the body features of an organism. So we can classify organisms on the basis of its physical features.

Onion root tips are often used to study mitosis because they grow very rapidly, which means that many cells are dividing. The very tip of the onion root ends in a structure called the root cap. The other end of the root attaches to the onion. A scientist is interested in determining whether an onion root tip grows from the base of the root or from the tip near the root cap. She counts the number of cells that are in one of the phases of mitosis at different distances from the root cap. What is the dependent variable in her experiment
Answer:
- Dependent variable: number of cells that are in one of the phases of mitosis
Explanation:
In an experiment, the independent variable is the variable that is not changed by the other variables that are being measured during the experiment (in this case, the independent variable is represented by the distances from the root cap). On the other hand, the dependent variable is the variable that is being measured/tested during the experimental procedure and, therefore, is 'dependent' on the independent variable. In consequence, in an experiment, the dependent variable is expected to change as a result of the manipulation of the independent variable.

Luisa went into the bathroom after her sister had a bath. It was full of mist and the mirror was covered with the a lot of liquid drops. What was the mist made of?
Answer:
Mist is made of water vapor.
Explanation:
The bathroom mirror and the fog that the bathroom presents after someone takes a shower, is formed by water vapor. This water vapor is formed by the hot water from showers, which evaporates. This water vapor is what forms the mist, however, when this mist touches the surfaces of the bathroom, such as the mirror, it becomes water again and that smothers the mirror. The mist becomes water when touching the mirror because of the difference in temperature between them, as the mist is hot and the mirror is cold. This happens through the condensation of water.

extinction, in which ecosystems change drastically
Explanation:
The emergence, growth, and extinction of a large clade, such as the dinosaurs, is an example of larger macroevolutionary patterns. This larger macroevolutionary patterns occur due to climate change. Extinction of organisms in which ecosystems change drastically that leads to unfavourable environmental conditions which decreases the population to the extinction of organisms.
