Competition occurs between species when _____.
they fight for mates
their niche is destroyed
they try to share the same niche
a new niche becomes available
Answer: The correct answer for the fill in the blank is- They try to share the same niche.
According to competitive exclusion principle, two species when present in the same area, try to compete for the same limiting resource like food. The species having better advantageous trait over the other survive and exclude the other one. In other words, the second species is either eliminated or shifts to some other niche.
This principle is also called Gause's principle.
Thus, competition occurs between two species when they try to share the same niche.
Answer:
they try to share the same niche

The weather department in Richmond is forecasting a snowstorm. What is likely to happen to the barometer and thermometer readings in Richmond?
A. Barometer readings will decrease, and thermometer readings will increase.
B. Barometer and thermometer readings will increase.
C. Barometer and thermometer readings will decrease.
D. Barometer readings will increase, and thermometer readings will decrease.
E. Barometer and thermometer readings will not change.
The correct answer is option D. Barometer readings will increase, and thermometer readings will decrease.
The barometers are the devices, which are used for the measurement of the pressure and the thermometer is a device, which is used for the measurement of the temperature. During snowstorm, the temperate is decreased and the pressure is high. So, the reading on the thermometer would decreased, and the reading on the barometer would be increased.

You visit a farm and notice that white chickens lay white eggs and colored chickens lay brown eggs, so you decide that only white chickens lay white eggs. What type of reasoning is this?
a) inductive
b) deductive
Answer
Inductive
Explanation
Its a logical process in which a number of premises all believed true or sometimes found true most of the time and combined to come up with specific conclusions. Its mostly used in applications that do involve behavior, forecasting and makes broader generalization that is considered probable. For example a speculation that all crows are black and each time a new crow is observed and found out that its black the assumption is increasingly confirmed. On the other hand if the crow is found not to be black then the assumption's found to be false..

The genes are very far apart on the chromosome.
All of the above are correct.
Select all that apply.

Fish, trees, and animals are important wildlife resources that we depend on for survival. Fish are a main source of food for many of the people in the world. Trees have been used to build and heat homes, make paper, and provide food for centuries. Humans hunt land animals such as deer, fox, antelope, and buffalo for food and other products. What can we do to protect wildlife resources so they will be around for future generations?
Answer:
harvest fast-growing trees, impose fishing limits, and impose laws to prevent poaching and illegal hunting
Explanation:
i got it right

what is the independent variable in this experiment
Answer: yes the expert is right
Explanation:
Final answer:
The independent variable is what the researcher manipulates in an experiment to see its effects on a dependent variable, such as applying different amounts of a new fertilizer to see its impact on plant growth.
Explanation:
The independent variable in an experimental study is the factor, property, or condition that the researcher manipulates or changes purposefully to explore its effects on a dependent variable. For example, if a researcher is testing the effects of a new fertilizer on plant growth, the type and amount of fertilizer applied (the treatment) would be the independent variable. The growth of the plants, which the researcher measures, would be the dependent variable. The researcher controls and changes the independent variable and then observes any changes in the dependent variable to determine the impact. In a typical experimental setup, the independent variable is introduced to the experimental group but not to the control group, which allows the researcher to compare the effects. It is crucial to hold all other factors constant so that any observed changes in the dependent variable can be attributed to the manipulation of the independent variable. For instance, using the previous example of plant growth, light, water, and soil conditions would need to be kept constant barring the fertilizer application.

The element hydrogen has three naturally occurring isotopes, H-1, H-2, H-3. What is the number of protons, neutrons, and electrons in H-3, or tritium?
Answer:
Tritium is one of the three isotopes of hydrogen which contains 1 proton, 2 neutrons, and 1 electron. Out of three isotopes, protium is the most abundant isotopic form of hydrogen constituting about 99.98 % of total isotopic form.
Tritium is a radioactive isotope of hydrogen having a half-life period of 12.3 years which is produced as a byproduct of fission in a nuclear explosion. Naturally, it occurs in a very trace amount.
It emits the beta particle which is having very low energy so cannot penetrate the skin but can be hazardous if inhaled or get absorbed in the skin.

The allele for a widow’s peak has complete dominance over the allele for a straight hairline (w). What is the probability of a man with a straight hairline (ww) and a woman with a widow’s peak (WW) having an offspring without a widow’s peak?
0 percent
75 percent
25 percent
50 percent
Option A is the correct answer.
D. 0 percent
Explanation:As the widow's peak is dominant over straight hairline (w). And the mother is homozygous recessive dominant for widow's peak. So, her all children receive one dominant W from their mom so they all will be having widow's peak.
Which statement is an accurate description of the relationship of rocks and minerals? A. All minerals are made of rocks. B. Geologically, minerals and rocks are exactly the same. C. Knowing which minerals are in a rock can help you identify and classify that rock. D. Almost all rocks are made of three or more minerals.
Final answer:
The relationship between rocks and minerals is that identifying the minerals within a rock helps to classify and identify it; rocks consist of minerals, which are their basic building blocks. So the correct option is C.
Explanation:
The question concerns the relationship between rocks and minerals in geology. The accurate description of this relationship is that knowing which minerals are in a rock can help identify and classify that rock. Rocks are aggregates of minerals, and most rocks are composed of a few common minerals, although some rocks are made up solely of one mineral. Minerals are the basic building blocks of rocks, and identifying the minerals within a rock is a fundamental skill for geologists. While seven common minerals make up 84% of the Earth's crust, there are over 5,000 known minerals that could be present in various types of rocks, including igneous, sedimentary, and metamorphic rocks.
