Answer 2
Scientists gather indirect evidence using seismic waves (Earthquakes) along with what is visible at Earth's surface. The correct option is 1.
What are seismic waves?
Seismic waves are caused by sudden movement of materials within the Earth, such as fault slip during an earthquake.
Seismic waves generated by earthquakes or explosions can travel through the Earth's interior, revealing information about the properties of the rocks and other materials they pass through.
In addition to seismic data, scientists use other indirect methods such as magnetic and gravitational field studies, as well as analyses of rocks and minerals found at or near the surface.
Scientists collect indirect evidence by observing seismic waves (Earthquakes) as well as what is visible on the Earth's surface.
Thus, the correct option is 1.

through muscle contractions
by using special hairs
by producing estrogen
through secretions of glands
Answers
Answer:
by using special hairs
Explanation:
When an egg pops out of an ovary, it enters the fallopian tube. Once the egg is in the fallopian tube, tiny hairs in the tube's lining help push it down the narrow passageway toward the uterus.

What is ONE major difference in the problems associated with obtaining measurements on the sizes or densities of animal populations versus plant populations?
Answers
I think one major difference with that is that animals can move around, go distances in search for food or mate, and thus make the animal densities per geography vary greatly. Birds migrate regularly, so their population densities tend to vary with seasons. Their mobility also depends on the availability of food, so animals go away if there are no food in the area.
Plants on the other hand don't move around faster (they can migrate by reproduction: it's their seeds moving around). Thus their densities tend to be more constant per season/life cycle.
A girl is born with hemophilia. Her dad also has hemophilia, but her mother does not.
What genetic explanation can you provide as to why the girl
suffers from hemophilia?
Answers
answer:
So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.
Explanation:
A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.
Hope this make sense!

A scientist is adding thermal energy to a sample of water. Using the Law of Conservation of Energy, what can you predict will happen? (3 points)
The water will increase in temperature beyond the amount of thermal energy that is added, because more energy will be created in this experiment.
The water will decrease in temperature as thermal energy is added, because it cannot create more energy or matter.
The water will not change its temperature because energy cannot be created or destroyed.
The water will increase in temperature in proportion to the amount of thermal energy that is added, but some will be lost to the environment.

what is the full form of tree
Answers
Explanation:
A tree or large tree is called a long-standing woody plant. In botany, the tree is one of the most durable plants that maintains its leaves by growing a stem or trunk. In some definitions, the use of the tree is such that it is the only woody plant. It is the only plant from which wood is obtained. It is not possible to determine the exact height of the trees, but overall the adult trees reach at least 6 meters [citation needed]. In the structure of the tree there are usually branches that are attached to a large trunk. Compared to other plant and animal species, trees have a long life. Some species of trees are more than 100 meters tall, and some live for thousands of years. Trees are important elements of natural landscape, gardening and landscaping. [1]

What type of organisms are most likely to be found as fossils?
Answers
Organisms with hard parts such as a mineralized shell, like a trilobite or ammonite, are much more likely to become fossilized than animals with only soft parts such as a jellyfish or worms.
Organisms with hard body parts such as a mineralized shell are much more likely to become fossilized as har parts are not fed by scavengers.
Types of organisms that are most likely to be found in the fossils have completely made up of hard bodies or at least some hard body parts.
The deposit of sediments and the finer the sediment deposited the likelier fossilization is to occurThe hard parts of organisms, for instance, bones, and teeth have had becoming fossils.Scavengers normally leave such hard parts, however, they also decay with time but this gives more time to be buried in sediments.
These hards parts have better chances than the organisms with soft body parts to be found in fossils.

For her science fair project, your little sister replicated one of Mendel's experiments. From a P0 pea plant with purple flowers and a pea plant with white flowers, she got 1 purple F1 hybrid (she had forgotten to water, so just one survived). From this self-fertilized F1 she got 8 F2 offspring. 7 were purple and 1 was white, for a 7:1 ratio. Did your little sister just disprove Mendel's laws
Answers
Answer: No, the 7:1 ratio is close to the expected 6:2 ratio even with the limited sample size.
Explanation:
Let the alleles be P (purple) and W (white).
The possible crosses are
PP x WW, PP x PW, PW x WW, PW x PW
the F1 is PP or PW
one F2 is white so the F1 must be PW and
the F2 are PP, WW, PW and
the expected 8 progeny are 2PP, 2WW, 4PW
Because 7/8 are purple, we can infer that P is dominant and W recessive, so the expectation is 6 purple, 2 white
The observed ratio is similar to the expected ratio, so we can’t say that this result disproves Mendel, particularly with a small sample.
7:1 is close to 6:2, even if the sample is smaller. We cannot invalidate Mendel with such a small sample size because the observed ratio was not statistically different from the anticipated ratio.
What is Mendelian Ratio?
The term "Mendelian inheritance" refers to specific patterns that can be observed in the way characteristics are passed down from parents to children. In the 19th century, the Austrian monk Gregor Mendel conducted thousands of tests with pea plants in order to develop these broad patterns. He did this in order to determine the genetic makeup of pea plants.
The frequency with which diverse phenotypes are produced as a result of any cross incorporating Mendelian traits. in particular, the three to one ratio that is displayed by the second generation of descendants from parents who are different from one another in regard to a single character.
