Answer 1
The answer is A. None of the other answers make sense. A is supported by the graph. There is only one section where the plants could be fossilized and there were very few that died that way.
Answer 2

Answer:

I was never really good at this until my teacher took the time and eplained things to me, so with what I now know, I started to cross out options that didn't make any sense, and was left with A

Imagine that you are a grain of pollen on a flower that cross-pollinates
the flower of another plant of the same species. Write a journal
entry in complete sentences describing your journey. Correctly
include each of these terms in your entry: pollinator,
pollen, pistil, stamen, anther, stigma, ovary, and eggs

Answers

Answer:

As a grain of pollen on a flower, I am responsible for cross-pollinating the flower of another plant of the same species. I began my journey on the stamen of one flower, where I picked up the pollen from another. I was carried to the pistil of the next flower and deposited the pollen on the stigma. I then traveled down the style to the ovary, where I fertilized the eggs, commencing the production of the next generation of this flower.

As a grain of pollen on a flower, I am a small but important part of the plant's reproductive system. I am carried from the stamen of one flower to the pistil of another flower by a pollinator, such as a bee or a butterfly. When the pollinator lands on the flower, I am transferred to the stigma of the pistil, where I will begin my journey to the ovary.

Once I reach the stigma, I begin to germinate and grow a pollen tube that will guide me down to the ovary. Inside the ovary, I will fertilize the eggs, which will eventually develop into seeds. This process is known as cross-pollination, and it is an essential part of the plant's life cycle.

As I make my way down the pollen tube, I am filled with excitement and anticipation. I know that I am playing a critical role in the plant's reproduction, and I am proud to be a part of this process. Once I reach the ovary and fertilize the eggs, my journey will be complete, and I will have helped to ensure the continuation of the plant's species.

What is the energy level of a liquid?

Answers

Answer:

The energy level of a liquid refers to the amount of energy that is stored within the molecules of the liquid. This energy can take various forms, including kinetic energy (the energy of motion), potential energy (the energy of position), and thermal energy (the energy of heat).

Liquids have more kinetic energy than solids. If you add heat energy to a liquid, the particles will move faster around each other as their kinetic energy increases. Some of these particles will have enough kinetic energy to break their liquid bonds and escape as a gas (evaporation).

In seals, the gene for the length of whiskers has two alleles. The dominant allele (L) codes long whiskers & the recessive allele (l) codes for short whiskers. If one parent seal is purebred long-whiskered and the other is a hybrid, what percent of offspring would have long whiskers?

Answers

Probably around 75% because one parent is a hybrid so it is half long and short and th other parent is long
It would most likely be around 75 becuase assuming that 1 seals genes is worth 50 percent and the others is also worth 50 percent than you have a 50 and 25 percent chance of long whiskers

Answers

Answer:Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.

There are two types of pollination

--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.

--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.

I need help with this Question A Big Year By Bob Kowalski Would you go to the ends of the earth to see a bird? What if it were a really special bird: one with beautiful feathers, an entrancing call, or a silly dance? What if seeing that one special bird would allow you to win a contest? If that contest doesn't get you on television or win you any cash prizes, would you still do it? For those who participate in the "Big Year," the honor of beating the previous record is the only reward they get or even want. A "Big Year" is a year in which a person attempts to see as many different species of birds as possible within a particular region. For most in North America who participate in a "Big Year," this region is the lower 48 American states, plus Alaska, Canada, and a couple of French islands off the Canadian coast. You may be thinking that looking at birds is silly, but just think about the numbers of the recent record holders and the commitment it takes to get these numbers. One recent "Big Year" winner managed to see 744 birds in one year, missing the record by just one bird. Big Year birders travel by train, plane, boat, car, bicycle, and of course, by foot. They can cover over 150 thousand miles to get numbers of sightings this high. They can also spend a small fortune. Just to clarify, the birds these contestants are counting are the number that they see in a particular year. You see, the contest is based on an honor system. No pictures or other evidence is required as proof of a sighting. Most birders take great pride in their reputation and their abilities to see or hear and then identify a bird. Usually, important sightings of the rare birds needed to get counts in the 700s are visited by hundreds of birders. It is pretty hard to cheat your way to a record-breaking year, but in general, few are interested in cheating. This honesty comes from the fact that most people who want to break such a record know the greatest rewards are not necessarily in winning. Such rewards are in being able to commit a year of your life to doing somethi Can someone answer these questions for me?
