Scientists analyzed data collected over a period of years in a game reserve in South Africa to test the hypothesis that competition with lions limits the abundance of leopards in the same community. The game reserve encompasses a variety of habitats, from open grassland to wooded areas around rivers and streams. It contains most of the indigenous mammal species and an adequate availability of their prey. For the most part, the leopards and lions show similar habitat preferences in the reserve.
The mass of the average lion is about three times that of the average leopard. The scientists analyzed several factors that might influence the abundance of each population, including the sizes of the animals preyed on by each species
Size of Prey Animal Percent of Leopards’ Prey (±2SEx¯) Percent of Lions’ Prey (±2SEx¯)
Small 34 ± 2 3 ± 1
Medium 63 ± 3 23 ± 2
Large 3 ± 1 36 ± 4
Very large 0 38 ± 3
Because competition with lions might affect the population size of the leopards, the scientists also analyzed data on the lion and leopard population sizes in the game reserve (Figure 1).
Required:
Describe what scientists mean when they refer to an ecological community such as that shared by the leopards and lions.
Answer:
The correct answer would be - these are the ecological community that shows the interspecific competition.
Explanation:
In this ecological community, both predators lion and leopards are living together and by the given data and information it is evident that they both share the same habitat and they both depend on the same prey for their food.
This cause competition between both lion and leopard for food and habitat. Such competition or interaction is referred to as the interspecific competitions negatively impacted by the presence of the other because they will have less food.
Answer
An ecological community refers to all of the interacting populations in a defined habitat.

sedimentary rock. Which of these processes would be the correct label to
replace the question mark?
Metamorphic rock
Sediment
Sedimentary rock
Erosion
?
A) Cooling
B) Deposition
C) Melting
D) weathering
Answer:
The process that would be the correct label to replace the question mark in this question is:
B) Deposition
Explanation:
Deposition takes place after erosion of sedimentary rock. At this stage, the eroded sedimentary rocks build up under high pressure heat, wind, ice, water, and other natural forces to originate the rock formation cycle once again. Naturally, after deposition, the igneous rocks, which have then layered up sedimentary rocks to become metamorphic rocks.

When people run quickly, they can sweat profusely. Their muscles undergo movement, and the loss of energy takes place. Based on this description, in which two ways is energy conserved when people run?
Heat energy is released from the body to the surroundings.
Heat energy is taken from the surroundings to the body.
Chemical energy is converted to mechanical energy that’s used for muscle movements.
Radiant energy is converted to mechanical energy that’s used for muscle movements.
Heat energy is converted to mechanical energy that’s used for muscle movements.
Answer: Chemical energy is converted to mechanical energy that’s used for muscle movements.
Heat energy is converted to mechanical energy that’s used for muscle movements.
Explanation:
According to the I law of thermodynamics, energy can neither be created cannot be destroyed but it can only change its form. In the given situation, the energy can only be conserved when it is not lost to the environment. The chemical energy is produced in the body in the form of ATP which is converted into mechanical energy to allow the movement of the muscles during running. So, chemical energy is converted into mechanical energy by this way. The heat energy when directly converted into mechanical energy to induce the movement of muscles the energy will remain conserved and will not lost to the environment.
Answer:
Chemical energy is converted to mechanical energy that’s used for muscle movements.
Heat energy is converted to mechanical energy that’s used for muscle movements.

Which of the following is a true statement? Physical property change is always better than chemical property change.
o Physical and chemical propery change can happen at the same time.
Chemical property change is better than physical property change.
Answer:
the second one
Explanation:
Sometimes it can be tricky to know whether or not a chemical reaction has occurred. For example, when you melt ice into water, you can write the process in terms of a chemical reaction. However, the chemical formula on both sides of the reaction is the same. Since the chemical identity of the matter in question is unchanged, this process represents a physical change.
Thus melting point is a physical property. On the other hand, flammability is a chemical property of matter because the only way to know how readily a substance ignites is to burn it. In the chemical reaction for combustion, the reactants and products are different.
none are better, depending on for what

Given the loss of farming jobs projected in the near future, distinguish at least two factors in a decision one might make to enter the field.
i cant process this lol no matter how much tiems read it
Answer:
this is the suggested answer
Explanation:
A correct answer will discuss two factors from among the following: one factor is despite the projected loss in farming jobs, these jobs are still essential and may still provide for a lucrative and successful career given that the median income level that is significantly higher than the national average. Another factor is the wide variety of careers in this general field, so the information on declining career outlook could be misleading, depending what specific career one is looking into. Another factor is the several training programs available to benefit those looking to enter this field, which can contribute to success.

A prospective groom, who is healthy, has a sister with cystic fibrosis (CF), an autosomal recessive disease. Their parents are normal. The brother plans to marry a woman who has no history of CF in her family. What is the probability that they will produce a CF child? They are both Caucasian, and the overall frequency of CF in the Caucasian population is 1/2500—that is, 1 affected child per 2500. (Assume the population meets the Hardy-Weinberg assumptions.)
Answer:
Explanation:
From the given information:
Since the parent are normal; Let assume that their trait is Pp
The affected sister will be recessive in nature, so the trait will be pp
Now, the husband who is the groom will be a carrier with a probability of 2/3 since her sister is affected.
Also, the wife will be carrying a heterozygous trait since she is normal as well.
However, using Hardy-Weinberg assumption:
[tex]q^2 = \dfrac{1}{2500}= 0.0004[/tex]
[tex]q = \sqrt{0.0004}[/tex]
q = 0.02
Recall that:
[tex]p+q =1 \\ p = 1 - q \\p = 1 - 0.02 \\p = 0.98\\[/tex]
Thus, [tex]p^2 = (0.98)^2[/tex]
[tex]p^2 = 0.9604[/tex]
[tex]2pq = 2 \times 0.98 \times 0.022[/tex]
2pq = 0.0392
Finally, the required probability that there will be an affected offspring amongst the family is:
[tex]= \dfrac{1}{4} \times \dfrac{2}{3} \times 0.0392[/tex]
[tex]= \dfrac{1}{153}[/tex]

You are tasked with characterizing responses to Epidermal Growth Factor (EGF) treatment of HeLa Cells. You grow HeLa cells then replace the culture media with media containing EGF at various concentrations, then harvest samples for Western blot analysis using an anti-phospho-MAPK antibody as a readout of receptor tyrosine kinase activity. As expected, your control (EGF treated cells) show a strong phopho-MAPK signal on your Western blot. What do you hypothesize will happen if you pre-treat HeLa cells with siRNAs (RNAi) against Ras prior to adding EGF and performing Western blot analysis with anti-phospho-MAPK
Answer:
The answer is "The EGF receptor will be activated but the signal will not be appropriate transduced"
Explanation:
It induces the replication of cell types, especially fibroblasts or epithelial cells. It enhances neuron variety's telling the difference, ripening, and survival. The proinflammatory cytokines of the EGF family are described by four disulfide bonds that confer adhesive properties. The EGF sensor is switched on and the signal is not transmitted correctly.
