Answer: A. predation
Predation is kind of interaction among species, in which one organism kills the other organisms in order to obtain it's food. The organism which feed upon other organisms is called as a predator and the the organism being consumed is called as prey.
The dorsal fin is a kind of camouflage to disguise prey organisms, so that the frogfish can obtain it's food by attracting and killing small sea creatures. Therefore, it is a predation type of interaction between the frogfish and other species of fish it attracts.
Which of the following is found in cancellous bone but not compact bone? A. osteocytes in lacunae
Answer: C) trabeculae
Trabeculae are found in the cancellous bone but not compact bone as, in the cancellous bone the trabeculae are the spaces creating in the tissue by the thin areas of the osteoblast cell. Cancellous bone are trabecular bone which has the higher surface area as compared to the mass ratio than the cortical bone because this is less dense and it makes more flexible.

HELP ASAPPP!!!!!! Jessica is a competitive swimmer, but she hates swimming at one particular pool because it is always so much colder than the others. What part of her brain allows her to determine the temperature difference between the pools?
The input from the temperature sensors of our body (and in this case skin) are processed in the central part of the brain known as the parietal lobe.
Other cortical processes occurring here are touch and pain as well as the interpretation of language and words together with the interpretation of signals from vision, hearing, sensory, motor and memory.
Our self perception and interaction with the world occurs here too.
When a scientist is conducting research about all the plants and wildlife in the Mojave Desert as well as the desert’s resources, such as water and soil, the scientist is studying
In this case, we have a situation where the scientist is describing an ecosystem. The ecosystem represents all the living organisms (flora and fauna), their environment, and the interactions that they all have between each other. In this case, we have the plants and animals being described, thus the flora and fauna, as well as the water and soil, thus their environment, so we have description of an ecosystem, or more specifically, the desert ecosystem of the Mohave Desert.
3. Explain why food webs with many species (biodiverse) are more resilient (stronger) than those with few species
Since there are more species they have more options on which ones to eat because food webs with many species (biodiverse) are more resilient (stronger) than those with few species.What is food web?
Food web is defined as a natural way of interconnection of food chain that shows graphically and it shows that in a ecological community who eats whom.
The food web is also known as consumer consuming system. The main advantage of food web is the organism present on top or the organisms who belongs to higher trophic level can provide food or feed the organisms from lower trophic level or from other food chain.
The permanent food web is increased due to the presence of large or complex food web. There are mainly three steps in a food web or food chain and they are producers, consumers, as well as decomposer.
The producer belongs to trophic level, the consumers belongs to second and third trophic level, and the decomposers belongs to fourth and fifth trophic level.
Therefore, Since there are more number of species they have more oppurtunity on which ones to eat because food webs with many species (biodiverse) are more stronger than those with few species.

Using site-directed mutagenesis, you have created a mutant form of chymotrypsin that has alanine substituted for the usual serine at position 195. Which of the following effects would your expect to observe? a. No effect or slight increase in affinity for substrate coupled to a complete loss of enzyme activity. b. A decrease in the affinity for substrate coupled to a decrease in enzyme activity. c. An increase in the rate of peptide-bond cleavage due to an increase in the rate of acid-base catalysis. d. An increase in the rate of peptide-bond cleavage due to an increase in the rate of covalent catalysis. e. A complete loss of enzyme activity due to the inability to bind substrate
The correct answer is - option E.
Serine may not be affected by the mutation as it has no part of the hydrophobic binding site so it won't affect the affinity of the binding of the substrate. The peptide bond-breaking would not occur without the catalytic end or part so the enzyme would be the complete loss of enzyme activity due to site-directed mutagenesis that is created from the chymotrypsin.
Thus, the correct answer is - option E.
Think about a situation that makes you feel very nervous or anxious. Describe how this makes you feel inside. What do you think is going on in your body?
I get very nervous when it comes to speaking infront of people. My heart starts to race and I begin to sweat a lot. The nerves in my body are getting fired up, sending my into fight or flight mode. My sympathetic system is activated
When I go up in front of a ton of people that are very judgy.
I am very shy.

How do geologists study direct evidence of Earth’s interior?
Answer: The correct answer is : Geologists have used two types of evidence, a direct one that are samples of rocks and an indirect one that is of seismic waves.
Explanation: Extreme conditions inside the earth have always prevented a very internal exploration. Direct evidence is obtained when forces inside the earth throw rocks at the surface from depths of more than 100km.
From the indirect evidence that seismic waves are, geologists have learned that the earth has several layers inside. Geologists observe the records of seismic waves and study how they travel through the earth, their speed and the route they take to determine the structure of the planet.
They collect direct evidence from rock samples and indirect evidence from seismic waves
