Which stimulus causes the roots of seedling to grow downard ?

Answers

Answer 1
gravity
Plant roots always grow downward because specialized cells in root caps detect and respond to gravity. This is an example of a tropism. A tropism is a turning toward or away from a stimulus in the environment. Growing toward gravity is called geotropism.

Charles has developed a new advertisement that can be used online. He tests how well it draws people's attention by closely
monitoring the eye movement of 1,000 test subjects as the new ad appears on their computer screens!
Charles finds that 97% of the test subjects' eyes were drawn toward the ad when it appeared. By comparison, only 50% of the test
subjects' eyes were drawn toward a box of plain text when it appeared instead. He concludes that the new ads are better at
attracting people's attention than old ads.

If an organism's gametes contain 25 chromosomes, how many chromosomes will their somatic (body cells) contain?

Answers

Answer:

Somatic cells are diploid, meaning that they contain two sets of chromosomes, one inherited from each parent

Explanation:

At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2

Once a fossil has been formed, it still might not become part of the fossil record. Describe two natural processes that might destroy the fossil.​

Answers

Once buried, the fossil and surrounding rock might undergo extreme pressure and heat, and the fossils could melt. Once fossils are formed, they might be washed away by streams, moved by glaciers, carried by scavengers, or caught in rockslides. Weathering by wind, water, and sun can destroy a fossil by wearing it away.

Answer:

the first one is by melting because of the extreme pressure and heat and the other way is being washed away or something

Calcium-41 has a half-life of 80,000 years. At the end of 240,000 years,
how much Calcium-41 would remain in a sample initially containing 60
micrograms? *
A 7.5 micrograms
B 60 micrograms
C 15 micrograms
D 30 micrograms

Answers

If the half-life is 80,000 years, then 240,000 years would be equivalent to three half-lives. In other words, the initial amount of the radioactive calcium-41 would have been reduced in half three times over. Mathematically, this can expressed as

calcium-41 remaining = initial mass of calcium-41 × (0.5)³.

Since we are given the initial mass of calcium-41, the amount of calcium-41 remaining after 240,000 years would be:

60 μg × (0.5)³ = 7.5 μg, or 7.5 micrograms.

7.5 is the answer I think hope this helps

Why might larger jaws and teeth become more common in jaguar species over time? In your response use the 4 principles of natural selection to support your answer. (Genetic variation, overpopulation, competition, and adaption) Please help it's due today

Answers

Answer:

Larger jaws and teeth may become more common in jaguar species over a period of time for a few reasons. To start off with, the genetic pool needs to prompt the species to have multiple offspring of different genealogy lines (non-inbred). Those offspring with the new attributes would have to adapt and survive. They wouldn't necessarily need to do better than the normal variation of jaguar, they just need to do well enough to mate. In terms of mating, the offspring with the mutation would have to mate with each other since the mutation would most likely be recessive. Over time, with more offspring that contain the mutation and keep breeding together, the recessive gene would become dominant (I think that's how that works) within the population. Once the population is high enough, there would be a competition between the normal variation and new variation of jaguars.  Assuming the new variation out-competes the normal variation, natural selection had occurred and you have a result.  I hope this helps!

Which body system is responsible for producing offspring

Answers

Answer:

The Reproductive System

Explanation:

In living things, the reproductive system is responsible for producing children. It is a group of hormones, tissues and organs that cooperate to promote the conception and development of new ones.

Men have a variety of reproductive organs, including the testes, epididymis, vas deferens, prostate, etc. Sperm production and distribution are facilitated by these structures. In women, the reproductive system includes the uterus, fallopian tubes, cervix, and vagina, among other structures.

These organs play an important role in the development of the egg during pregnancy, fertilization, implantation of the fertilized egg, and the growth and development of the fetus. Additionally, the reproductive system contains hormones that control reproduction, such as testosterone in males and estrogen and progesterone in females.

Answers

Answer:

The correct answer is - substitution.

Explanation:

Substitution mutations are the point mutations that are the mutations that least likely affect the trait of an organism or have no effect at all. Substitution mutations take place when there is only one nucleotide base is substituted by another nucleotide base in the  DNA or RNA of an organism's genome.

In this case, there is no effect found on the protein formed by these DNA sequences. These substitution mutations generally found in somatic cells and have little to no effect at all.
