Then write how sponges an Cnidarians are alike and different?
Differences:
Cnidarians have groups of similar cells that work together as tissues, while sponges have no tissues, only disconnected regions of specialized cells.
Similarities:
They contain nematocyst (cells that sting)
some are sessile/free swimming
Some corals have a symbiotic relationship with algae, they need to grow in shallow waters so that light can penetrate for the algae to photosynthesize.
Mountain chains in northern Europe and West Africa match the Appalachian Mountains in terms of their ages and the sequences of rock layers that make them up. in 3-5 sentences analyze these observations and explain what conclusions can be drawn from them.
According to the statement, it can be concluded that the three mountains were formed around the same geological era. Additionally, they have similar layers due to the sedimentation and metamorphization processes.
Since its emergence, the Earth has experienced different physical and chemical phenomena that have influenced changes in it. In the case of the lithosphere and the Earth's crust, they have been influenced by phenomena such as
Volcanism The rock cycle The wind The rainfall Among other
Additionally, geologists have developed methods of studying the crust to know the age and composition of the layers of the Earth's crust. According to this, it can be established that these three layers are of the same age because their composition of layers is studied and the materials and distribution of the layers match, that is, they were formed at the same time.
This coincidence in distribution is explained through the processes of sedimentation of materials and their metamorphization.

What would happen to the rate of activity if you place Pepsin in the small intestine with a pH of 6?
Answer:
When it reaches the duodenum, though, it assumes an inactive form as the pH rises above 6. Pepsins are secreted by Brunner's glands of the duodenum, and the crypts of Lieberkühn of the small intestine secrete an aqueous fluid.
You will create a molecular clock model for an arthropod gene. Follow these guidelines to make your model:
Your timeline will span from 90 million years ago to the present. The common ancestor in your model is an arthropod that lived 90 million years ago. The gene that you’ll track codes for a protein in the species’ venom.
The DNA sequence you’ll track contains 10 nitrogen bases. You can choose the order of the bases and where the mutations occur.
This gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. To build your model, calculate the estimated time period it takes for 1 base pair to mutate.
The first time period will only show the common ancestor. At the beginning of the second time period, three lineages will diverge from the common ancestor, each with a different mutation in their gene sequences.
The first and third descendant species will survive for the rest of the timeline. The second descendant species was extinct 50 million years ago.
Calculate how long it will take for one full base pair mutation to occur. Explain your reasoning by constructing a mathematical equation.
Answer:
The mutations occur at a rate of 0.56 base changes every 1 billion years. If this rate stays consistent, the mutation rate can be used to determine when different lineages of a particular species split
Answer:
It takes about 17.1 Million years for a base pair to mutate at a rate of 0.76 base pairs. To get the time it takes for one full mutation to occur, you must divide 17.1 to 0.76 and multiply it by 1. So, (17.1/0.76)×1=22.5. It would take about 22.5 million years for one full base pair mutation to occur. Having this being said, the first descendant with one base pair mutation would change after 22.5 million years from the common ancestor. For the second descendant, it would take 45 million years as 22.5 time 2 is 45. 5 million years later, the second descendant will become extinct while the first descendant survives. The third descendant will take about 22.5×3= 67.5 million years. Now, the first and third descendants will survive while the second descendant is extinct.

A zombie apocalypse wipes out almost the entire human species before the zombie threat is eliminated. It appears that only a group of 100 people who were at a family reunion on an uninhabited island survived. They returned to the mainland completely unaware of what had happened to everyone. Answer the following questions regarding the few survivors that now begin to rebuild the human population.
Certain traits will have been lost from the gene pool forever. Some may be obvious, like people with red hair and double jointed thumbs. Others will be less obvious, like the ability to process cholesterol or being allergic to peanuts.
a.) Which of the following best describes the mechanism of microevolution that has altered the human gene pool? Explain.
b.) Despite an abundance of habitat, why will it be difficult for the human species to recover in numbers?
c.) A straggler with green eyes stumbles into the last remaining human outpost. The green eye trait did not exist in the outpost before her arrival, but it does now. What is the name of this mechanism of evolution? Explain.
Answer and Explanation:
A. Hello. You did not enter answer options. However, we can state that mutation, natural selection and genetic drift will be the microevolution mechanisms that will affect the gene pool of these humans. This is because the new environment and the small number of living beings, will make this population completely susceptible to all these evolutionary factors, which will affect, in different ways, the gene frequencies in a population.
B. As the amount of living beings and human beings has become very small, the world will have a low genetic diversity. This will make it difficult for these humans to adapt to the new environment and will make them more susceptible to possible diseases that will arise in this new environment. This will make these humans more fragile and make it harder for them to multiply.
C. The evolution mechanism is the Gene Flow. Gene Flow refers to the exchange of genetic information between individuals in a population, through the donation of gametes that occur in reproductive processes. In this case, we can consider that the individual with green eyes, upon arriving in the community with individuals without green eyes, began to reproduce descendants, who, upon receiving the gametes responsible for green eyes, began to populate this community with this characteristic.

Which substance, maple syrup or vegetable oil, has a higher viscosity? Explain how you know the answer.
Answer:

Explanation:
This is because viscosity is simply the resistance of a fluid to flow. A thicker fluid is more resistant than a lighter one. In this case maple syrup is thicker than vegetable oil thus more viscous than it.

What does the term segmentation mean?
animal in which the mouth forms second in development
trait in which an animal has repeating body parts able to be specialized for different function
animal in which the mouth forms first in development
trait in which the nervous system is concentrated in one end, forming a head
Answer:
trait in which an animal has repeating body parts able to be specialized for different function
Explanation:
Segmentation is a characteristics of many living organisms. Segmentation is referred to as the division of certain body part of an organism into sections. This section is repeated as many times as possible on the animal/plant.
The segment divides the part into specialized units that performs differing functions. The different functions define the organism, hence, segmentation is very important in development.

How do we make a new gene
Answer:
Well to make a new gene, theoretically you would need to mutate your DNA of some sort.
Explanation:
Genes come naturally from your parents. And if you want a new gene that you can say "control" like being tall or having a high/low metabolism, you would have to rearrange or "mess around" with your DNA.
