Which two organs of a plant interact to cause seedlings to grow upward

Answers

There's tropism and stimulus, for starters. Gravity, light, and touch can all be used as stimuli. So it is debatable... If the plant is reaching upwards towards a window that is above it... It would then be light, and the plant's response would be to reach upward.

Write down a mechanism for increasing genetic variation in BOTH eukaryotes and prokaryotes.

Answers

Answer:

Genetic variation mechanisms are different in prokaryotes and eukaryotes, Transformation, transduction, and conjugation in prokaryotes whereas crossing over, random assortment, and random fertilization in eukaryotes.

Prokaryotes:

Prokaryotic cells can lead to genetic variation by recombining their genetic material. In prokaryotes, horizontal gene transfer (HGT), in which gene transfer from one organism to another in the same generation. The three most common ways of HGT are transformation, conjugation, and transduction.

Eukaryotes:

Eukaryotic organisms can perform either sexual and asexual or both reproduction in which they are able to transfer genetic material (DNA) to their offsprings. Such transfer of genetic material process is called vertical gene transfer. In sexually reproducing organisms, independent assortment during zygote formation, a mutation in genes, and crossing over during prophase 1 in meiosis is the process that increases the chances of genetic variation.

Because autotrophs produce their own food, they are sometimes called producers.Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs. Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria.

Estimate the sum of the masses: 56.9kg, 43.9kg, 60.5kg, 29.8kg​

Answers

Answer:

191.1 kg.

Explanation:

The total mass of all these objects can be determined by adding all the masses present in the question. 191.1 kg is the value of total masses when the given masses such as 56.9kg, 43.9kg, 60.5kg and 29.8kg​ are added with each other. This value is considered as the total sum of all masses so we can say that the total value is obtained after all the masses are combine or added together.

The current answer is - Deep.

Explanation:

If the water becomes denser, movement of water below the surface, and surface water is cool then Deepwater currents are formed. These currents are formed mainly due to differences in density, temperature and salinity.

These currents move towards the equator from the poles that carry cold water slowly than the surface water currents. It is due to density difference and temperature difference in the water.

4. The inner membrane of the mitochondria is impermeable to ions. How does this fit with what
you've learned about membrane structure? Why is this important to cellular respiration?

Answers

Answer:

The inner mitochondrial membrane contains proteins involved in the electron transport chain. This chain releases energy that is then used to generate an electrochemical gradient, which is subsequently used to synthesize ATP

Explanation:

Mitochondria are membrane-bound organelles that have an inner membrane separated from an outer membrane by the intermembrane space. Moreover, the mitochondrial matrix is located within the inner membrane. The inner mitochondrial membrane contains proteins involved in the electron transport chain and ATP synthesis. Oxidative phosphorylation (electron transport chain) is the third stage of cellular respiration in aerobic organisms in which ATP is generated by transferring electrons from NADH or FADH2 to O2 by a series of electron carriers located in the inner mitochondrial membrane. The trans-membrane complexes of electron carriers are multiprotein enzyme complexes (I–V) and electron carriers (i.e., coenzyme Q10 and cytochrome c) required for the communication between complexes. The electron transport chain is coupled to proton transfer from the matrix out to the intermembrane space, thereby generating a proton gradient which is then used by ATP synthases to synthesize ATP​.

Natural selection was acting on the population of radish plants. Which of the following DOES NOT satisfy a condition of natural selection as it relates to our radish populations?

a. there was a purple phenotype and a white phenotype
b. the R allele produced a white plant, and rr produced purple plants
c. competition was affecting the reproductive success of at least one of the morphs
d. our populations of radishes were small
e. all of the above are examples of conditions necessary and sufficient for evolution by natural selection

Answers

Answer:

d. our populations of radishes were small

Explanation:

Natural selection is a type of evolution that allows only individuals with favorable characteristics and better adapted to the environment to survive and reproduce offspring with the same favorable characteristics. In this case, to observe a population where natural selection is taking place, population sizes can be disregarded, as this is not a condition for natural selection to take place. However, the other conditions presented in the response options are necessary for natural selection, since it is necessary that there are different phenotypes and genotypes in the population and that competition between them promotes the survival of one group at the expense of the other.

2. Which types of halogen compounds are known to contribute to ozone depletion?
O A. Chlorofluorocarbons
O B. Salts
O C. Alkali metals
O D. Oxides

Answers

Answer:

A. Chlorofluorocarbons

Explanation: short answer

Answer:

A. Chlorofluorocarbons

Explanation:

Halogens are a chemical family containing fluorine, chlorine, bromine and iodine; any carbon compound containing them is known as a halocarbon. While all halogens have the ability to catalyze ozone breakdown, they have an unequal impact on the ozone layer. A catalyst is a compound which can alter the rate of a reaction without permently being altered by that reaction, and so can react over and over again. In this fashion it is estimated that one molecule of chlorine can degrade over 100,000 molecules of ozone before it is removed from the stratosphere or becomes part of an inactive compound. These inactive compounds, for example ClONO2, are collectively called 'resevoirs'. They hold chlorine in an inactive form but can release an active chlorine when struck by sunlight. The relative potency of the different halogens depends a great deal on the stability of the resevior compounds. Hydrogen fluoride, HF, is so very stable that fluorocarbons have relatively no known impact on ozone. Bromine resevoirs, such as HBr and BrONO2, are much more easily broken up by sunlight; causing bromine to be from 10 to 100 times more effective than chlorine at destroying ozone. From 30-60% of bromocarbons released to the atmosphere are man-made (methyl bromide fumigants and halon fire extinguishers) and both compounds will soon be restricted by international agreement.

In an asexual species, a beneficial allele and a deleterious allele are in linkage disequilibrium. The selection pressure for the beneficial allele is lower than the pressure of purifying selection, so the beneficial allele is being lost from the population. What is this an example of

Answers

Answer:

selective interference

 

Explanation:

Natural selection acts on genes that are inherited together, which is the case for species of asexual reproduction (where genes are inherited together by clonal offspring).  In asexual species, linkage disequilibrium (i.e., non-random association of the alleles of different loci), can be understood in a similar mode in terms of population allele frequencies. Selective interference underlies the association between beneficial mutations and surrounding sites which are subject to deleterious mutations. It has been shown that asexual species adapt at a slower rate than species of sexual reproduction. In sexual species, selective interference could be bypassed through the mechanism of recombination during meiosis (although there is not conclusive evidence of this). In asexual species, different deleterious and beneficial mutations are generally fixed, whereas beneficial mutations are generally spread and fixed in species of sexual reproduction.

Determine whether each statement describes mitosis, melosis, or both mitosis and melosis.

Answers

Answer:

This question is incomplete as it lacks statements, the statements and the answers are as follows:

occurs in organisms that sexually reproduce - MEIOSIS

occurs during growth and development - MITOSIS

the DNA is replicated - MITOSIS AND MEIOSIS

occurs in all organisms - MITOSIS

the number of chromosomes remains the same - MITOSIS

the number of chromosomes reduces by half - MEIOSIS

Explanation:

Meiosis and mitosis are both types of cellular divisions that occur in living cells. Mitosis involves the formation of two (2) daughter cells that are genetically identical to the parent cell while meiosis involves the formation of four (4) daughter cells that are genetically different from the parent cell.

The following are characteristics of the two division processes based on this question:

MITOSIS:

- It occurs during growth and development of an organism.

- it involves DNA replication

- it occurs in all organisms since every living organism undergoes growth and development.

- the number of chromosomes after mitosis remains the same in the daughter cell i.e. 2n remains 2n

MEIOSIS:

- It occurs only in organisms that sexually reproduce.

- it also involves the replication of DNA

- The number of chromosomes in the daughter cells is reduced by half i.e. 2n to n.
