In guinea pigs, the allele for short hair is dominant to long hair. A guinea pig with short hair is crossed to one that has long hair. Over a period of years, a scientist keeps records of the offspring and finds that 44 of them have short hair and 46 of them have long hair. Based on this data, what are the genotypes of the parents:
1. HH x hh
2. Hh x hh
3. HH x Hh
4. hh x hh
I would choose Option 2
about 50% chance that the dominance is in, but when it is, its dominant, of course.
no other Option can give you a 50% chance
in 1 its always there, in 3 as well, in 4 never
Deforestation can cause all living organisms to die. *
True
False
Answer:
False
Explanation:
usually,all animals do not die during deforestation. only few animals die. Actually, deforestation is the factor that leads to nature to regenerate itself. Through resistance and resilience, many new organisms are evolved. As evolution and extinction is the two side of coin, deforestation does not cause all animal to die.

How does survivorship relate to an individual's fitness?
Answer:
Ecologists use survivorship curves to visualize how the number of individuals in a population drops off with time. In order to measure a population, ecologists identify a cohort, which is a group of individuals of the same species, in the same population, born at the same time.
The higher the survivorship of an organism, the higher the fitness of the organism
What is survivorship ?The term survivorship refers to the ability of an organism to live long in its habitat and reproduce. This is related to the fitness of an organism which is its ability to survive to the next generation.
Hence, the higher the survivorship of an organism, the higher the fitness of the organism and vice versa.

Are viruses alive?
Answer: As for now, no, it is not clarified but most biologists say no. Because viruses don’t grow, aren’t made out of cells, can’t stay in a stable state, nor can they make their own energy. Most living things do these things, so the are classified as nonliving.
Hope this helps, good luck! :)
which examples represent abiotic factors affecting biotic factors? Check all that apply
Answer:
ash from a volcanic eruption kills new plant growth.
warm water from a nuclear power plant causes overgrowth of algae.
a river floods and deposits tree pollen along its banks.
Explanation:
Ecosystem consist of biotic and abiotic elements. Biotic refers to all living organisms while abiotic refers to all non-living elements of the environment. Living organisms depends on abiotic factors such as light, temperature, water and soil etc for their growth and survival. In the above answer, Ash of volcano, warm water and rivers are abiotic elements while plant, algae and pollen are biotic elements.
What is ecological succession?
A. Change that happens over time in an ecological community
B. A way a life
C. One person giving another person power
Answer:
A. Change that happens over time in an ecological community
Explanation:
Ecological succession is the change that happens over time in an ecological community. So, option (A) is the answer.
Answer:
A. Change that happens over time in an ecological community
Explanation:
Ecological succession is the gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing.
There are two main types of succession, primary and secondary.
Primary succession is the series of community changes which occur on an entirely new habitat which has never been colonized before. For example, a newly quarried rock face or sand dunes.
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. For example, after felling trees in a woodland, land clearance or a fire.

There are the same amount of carbon atoms on Earth now as there were in the past, but there are more in the atmosphere ever before. What explanation do you have for this?
The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years.The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
What does the theory of evolution tell us about living things?
A) The environment can make them change rapidly over a short period of time. B)They create fossils when they die
C)Their environment makes them change slowly over time.
D)They can give us clues about extinct species. (science 7th grade) (100 POINTS)
Answer:
Their environment makes them change slowly over time
Explanation: I took the test and got it correct.
The agents of wethering erosion deposition and the rock cycle will slowly change the fossils over time. They may damage them or burry them deep into the layers of earth. Over time, as they age, new landforms will me made ontop of them. This is why they use the fossils to determine the age of the land. I hope this helps :)

The chart below demonstrates the number of genetic differences between 9 species. Which two species are least closely related to each other according to the information provided?
Hi. You did not submit the chart to which this question refers, which makes it impossible for it to be answered. However, I will try to help you as best I can.
Generally speaking, we can state that the two species that are less genetically related are those that present more genetic differences between them. This is because the number of genetic differences is greater in species that have no genetic relationship, or that have a very weak genetic relationship.
In this case, to answer this question, you need to assess which two species, shown on the chart, have the greatest number of genetic differences between them.
