Sunroof was left open in my car during a thunderstorm back in May. Needless to say the front seats have had a rough recovery. Right now they're extremely hard and lost their shine. Are there any products to restore (or at least attempt to) the leather? Thanks

So I am tutoring a child in 8th grade math, and a website I went on for examples gave this equation:

Solve 5x - 4 - 2x + 3 = -7 - 3x + 5 + 2x

Now the website says the answer is -1/2 but every time I do it I get -1/4.

Is the website wrong or am I doing something wrong?

I've been exploring career options lately and as I tour colleges I've realized I think I might want to become an admissions counselor. What do you have to major in to do so?

Blood pressure forces fluid through the walls of a cluster of capillaries called the __________, and it collects in the cup-shaped __________.

Which of the following resting pulse and resting blood pressure results would be typical of a well-conditioned athlete?

72 and 150/90

48 and 110/80

66 and 120/95

84 and 110/75.

I'm confused which it would be and why??

Thanks!!! :)

Identify the reproductive barriers for each example below, Indicate whether each is prezygotic or postzygotic, and the specific type within the subset:

A long-eared owl male has a long and low hoot to attract the females.  However, all of the short-eared females find his call unappealing.

A nine-spine stickleback male (fish) deposits his sperm on the egg mass of a red-bellied dace female (fish).  However, the sperm were unable to penetrate the egg’s jelly coat, and fertilization did not occur.

A population of 100 fish in an aquarium consists of 49 homozygous dominant green individuals, 42 heterozygous green individuals, and 9 white individuals.

What are the frequencies of the three genotypes in the population?

What are the frequencies of the green and white alleles in the gene pool?

If the population is at Hardy-Weinberg equilibrium, what will the genotype and gene frequencies are in the next generation of fish?

Thanks!!! :)

I just got my eyebrows waxed for the first time about an hour ago, and on both of my eyes I have thick red lines right above my eyelid. Is this normal?

Which type of selection? (directional, disruptive, or stabilizing)

In a bird species, individuals with average-sized wings survive storms more successfully than other birds in the same population with longer or shorter wings.

The thickness of fur in a bear population increases over several generations as the climate in the region becomes colder.

(A) RNA polymerase can bind to the promoter, and expression will occur.

(B) RNA polymerase can bind to the promoter, and expression will not occur.

(B) RNA polymerase cannot bind to the promoter, and expression will occur.

(D) RNA polymerase cannot bind to the promoter, and expression will not occur.

Thank you!! :)

While DNA and RNA are both nucleic acids, they are not identical.  List the names of the nucleotides that are used for each of these nucleic acids.

Here is a question I was given in my biology class:

Muscular dystrophy is a sex-linked recessive disorder. A man with muscular dystrophy marries a woman who does not have this disease.

I understand that the genotypes of the father and mother would be XdY and XdXD. What I am confused with is what would the genotypes and phenotypes be of their offspring??

Thanks!! :)

I am having a hard time understanding the process of mitosis! I was given the following question in my biology class:

Mitosis results in 2 identical daughter cells. If the original cell has 40 chromosomes in G1 of interphase, how may chromosomes will be in each of the 2 daughter cells at the end of mitosis?

Any help would be appreciated. Thanks so much!

Water and glucose can't pass through the plasma membrane without help. But steroids can easily cross the membrane.  Can someone please explain why this is? Thanks!

(A) Which component in a prokaryotic cell is responsible for protein synthesis?

(B) Which structure propels the cell?

Thank you!!!

I'm trying to work on my biology homework, but I am confused with some basic biology questions? I've looked through my textbook but can't seem to find answers. Any help is appreciated, thanks!

The atom of oxygen in a water molecule is held to the hydrogen atoms of the same molecule by __________ bonds.

Molecules of water are attracted to each other and held close by ___________ bonds.

If water molecules are disrupted (for example by boiling), which of the bonds are more likely to break and why?
