Which additional claim can be BEST supported by the evidence from the skulls in the whale fossil record?
O A. The fossil record shows differences in the skulls of the mammals, which shows that they are from three separate species that all
lived at the same time.
B. The fossil record shows similarities in the skulls of the mammals, which shows that they must have had similar habitats and
environments
C. The fossil record shows that some mammals evolved so that their nostrils are further at the top of their skull for better breathing
while in the water.
D. The fossil record does not give enough evidence about the mammals to determine if there is a relationship between the three
skulls.

Answer: The basic theme of whale evolution is the development of large animals from much smaller ancestors, and nowhere is this more evident than in the case of multi-ton sperm and gray whales, whose ultimate forebears were small, dog-sized prehistoric mammals that prowled the riverbeds of central Asia 50 million years ago. Perhaps more intriguingly, whales are also a case study in the gradual evolution of mammals from fully terrestrial to fully marine lifestyles, with corresponding adaptations (elongated bodies, webbed feet, blowholes, etc.) at various key intervals along the way.

Can someone do this quick?
Answer: A.
Explanation:
Palisade mesophyll cells contain the most amount of chloroplasts with an average of 30–70 chloroplasts per cell so they will be number 2 in the graph.
Spongy mesophyll cells contain less chloroplasts than their palisade counterparts to enable them have a larger surface area for gas diffusion.
The guard cells have the least amount of chloroplasts on average and so will be number 1. on the graph.
describe what is happening at each phase of meiosis
The process of meiosis takes place in two phases. Meiosis I; Meiosis II; Phases of Meiosis 1 and Meiosis 2. During meiosis I, a cell is divided into two, and in meiosis II, further division takes place, resulting in a total of four haploid cells. Before the start of the process, the parent cell goes through a stage of preparation called the interphase.

Mr. Powell is demonstrating the water cycle. He shapes mountains out of clay on one end of a glass aquarium to represent land. He then pours some water into the aquarium and places a glass lid on it. Next, he turns on a lamp above the aquarium and, finally, he places a container filled with ice on the glass lid. In this model, which choice correctly identifies evidence of condensation?
a - water droplets falling on the clay
b - less water in the bottom of the aquarium
c - water running from the clay into the water
d - water forming on the lid under the container
PLEASE HELP!!!!!! this is due in 5 mins and this is my only question left o_o
Answer: d - water forming on the lid under the container
Explanation:
Condensation is the process that describes the change of state of water from gas to liquid. It happens in the water cycle when water vapor gets to the atmosphere and due to the lower temperatures turns into liquid water that then forms clouds.
In the demonstration, the container is meant to be the clouds so when water forms under the container, that is condensation happening because the water vapor has not turned back to liquid after leaving the aquarium water as water vapor.

The granite boulders in Rocky Mountain National Park are a favored place among talented climbers who specialize in the art of bouldering, or climbing harder (but shorter) routes without tying into a rope. Climbers have taken to (illegally) stashing foam crash pads underneath the boulders but marmots and other rodents chew up the pads and the litter is spread by the wind. Why would the park be overused in this manner
Answer:
Follows are the solution to this question:
Explanation:
The National Park for Rocky Mountain is among the nation's best popular national parks. Rich fauna wandering the valley and also some derisive recreational sports on the planet including its majestic peaks throughout every way is no surprise that each year upwards of 3.5 million people flocks to this park. Throughout this issue, the park would be overplayed as described, since the marginal private expense of using the parks is less than those of using the park at a marginal cost.

How does a loess affect the environment around it?
Answer:
Because loess is deposited from the atmosphere it provides an important geologic archive of past atmospheric circulation that can be used to test atmospheric circulation models
Explanation:
Answer:
Loess often collects in river headwaters, and subsequently gets carried to riverbeds. The buildup can be so dense, that it diverts the water over the adjacent flood plain. This may result in the flooding of rivers.

In this project, you will use reference materials and Internet sites to do research on a specific type of
genetic modification: genetically modified foods. Suggested references are listed at the end of this
document to help you with this project.
Using your research, you should be able to answer these questions:
1. What are genetically modified foods?
2. What crops are typically genetically modified?
3. Why are crops genetically modified?
4. How are crops genetically modified?
5. How do genetically modified foods affect society and the environment?
You will then share what you have learned by preparing a multimedia presentation. Your multimedia
presentation should include a title slide, a number of content slides that include specific information about
genetically modified foods, and a slide that lists the sources you used in your research.
Answer:
Genetically modified foods, also known as genetically engineered foods, or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering.
The most common GMO crops include soybean, maize, cotton, canola, and alfalfa. The following GMO crops were also planted in different countries in 2018: papaya, eggplant, potato, apple, safflower, pineapple, and sugarcane.
For centuries, farmers have bred crops for certain desirable traits. Genetically Modified (GM) crops offer improved yields, enhanced nutritional value, longer shelf life, and resistance to drought, frost, or insect pests.
Genetic modification of plants involves adding a specific stretch of DNA into the plant's genome, giving it new or different characteristics. ... The gene of interest is transferred into the bacterium and the bacterial cells then transfer the new DNA to the genome of the plant cells
GMOs have helped farmers reduce their environmental footprint by allowing them to use fewer inputs and enabling a shift to reduced tillage. These practices have led to less time spent on a tractor, less fuel used and fewer emissions.

This pedigree chart tracks the inheritance of a recessive trait that is not sex-linked. Based on the information in the chart, which of the following statements is true about individuals 3 and 4?
At least one is hete rozygous for the trait.
They are both hom ozygous dominant for the trait.
They are both hete rozygous for the trait.
At least one is hom ozygous for the trait.
Answer:
C. They are both heterozygous for the trait.
Explanation:
It is not possible for both parents to be hom ozygous dominant, as that would only produce hom ozygous dominant children, and from the chart they have one child that is recessive.
It is not possible for only one parent to be heter ozygous, as again, that would only produce dominant children.
Lastly, it is not possible for only one to be hom ozygous, because that again would only result in dominant children.
Pairing two heter ozygous parents would result in a 25% chance of a recessive child.
