Describe & explain why the effect of temperature as a
limiting factor for photosynthesis is different to the
effects of Co2 and light intensity.​

Answers

Answer 1

Answer:

Although  the  light  dependent  reactions  of photosynthesis     are    not     affected     by changes in temperature, the light independent   reactions  of   photosynthesis are dependent  on  temperature.  They  are reactions  catalysed  by  enzymes.  As  the enzymes approach their optimum temperatures  the  overall  rate  increases.  It approximately   doubles   for   every   10°C increase    in    temperature.    Above    the optimum  temperature  the  rate  begins  to decrease, as enzymes are denatured, until it stops.

Explanation:

At  low  light  intensities,  as  light  intensity increases,the  rate of  the  light-dependent reaction,and   therefore   photosynthesis generally, increases proportionately (straight    line    relationship).    The    more photons  of  light  that  fall  on  a  leaf,  the greater     the     number     of     chlorophyll molecules  that  are  ionised  and  the  more ATP   and   NADPH   are   generated.   Lightdependent  reactions  use  light  energy  and so    are    not    affected    by    changes    in temperature.As light intensity is increased further, however, the rate of photosynthesis is eventually  limited by some other factor. So the rate plateaus. At very high light intensity, chlorophyll may be damaged and the rate drops steeply (not shown in the graph).Chlorophyll ais used in both photosystems. The wavelength of light is also important. PSI absorbs energy  most  efficiently  at  700  nm  and  PSII  at  680  nm.  Light  with  a  higher  proportion  of  energy concentrated in these wavelengths will produce a higher rate of photosynthesis.An    increase    in    the    carbon    dioxide concentrationincreases  the  rate  at  which carbon  is  incorporated  into  carbohydrate in  the  light-independent  reaction,  and  so the    rate    of    photosynthesis    generally increases until limited by another factor.As    it    is    normally    present    in    the atmosphere  at  very  low  concentrations (about  0.04%),  increasing  carbon  dioxide concentration  causes  a  rapid  rise  in  the rate  of  photosynthesis,  which  eventually plateaus   when   the   maximum   rate   of fixation is reached.

This fly has 14 chromosomes in its cells.7 maternal chromosomes and 7 paternal chromosomes.Assume you are a microscopist viewing this fly cells that are undergoing meiosis. Conclude the number of chromosomes/chromatids at the end of meiosis 1 as well at the end of meiosis 2. please answer!!!!!

Answers

Answer:

23 pairs in meiosis 1 and 23 numbers in meiosis 2.

Explanation:

There are diploid number of chromosomes means double number of chromosomes at the end of meiosis 1 while on the other hand, at the end of meiosis 2, there are haploid number of chromosome means half number of chromosomes in each daughter cell. In humans meiosis 1, there are 23 pairs of chromosomes that is diploid in nature but in the end of meiosis 2, there are only 23 chromosomes in each daughter cell which is haploid in nature.

Decomposers are important in the environment because they
A. convert large molecules into simpler molecules that can then be recycled
B. release heat from large molecules so that the heat can be recycled through the ecosystem
C. can take in carbon dioxide and convert it into oxygen
D. convert molecules of dead organisms into permanent biotic parts of an ecosystem

Answers

Answer:

D

Explanation:

Decomposers are important in the environment because they convert molecules of dead organisms into permanent biotic parts of an ecosystem. So, the correct option is (D).

What are Decomposers?

Living organisms such as micro-organisms that convert dead plants and animals into humus are known as decomposers. Fungi and bacteria fall in this category. It recycles and converts the dead matter into humus which mixes with the soil of the forest. It provides essential nutrients to the plants. It is also known as detritivores.

There are four types of decomposers, namely

FungiInsectsEarthwormBacteria

These types of organisms decompose or break down organic matter such as the remains of dead organisms, carrying out the process of decomposition, which occurs after the death of all living organisms.

They are also called reducers because they are able to remove or degrade dead bodies of organisms and because of their small size they are known as micro consumers.

Thus, Decomposers are important in the environment because they convert molecules of dead organisms into permanent biotic parts of an ecosystem. So, the correct option is (D).

You are walking through a mixed evergreen-deciduous forest, where approximately 10 percent of the trees are eastern hemlocks, a species of evergreen tree that casts very deep shade on the forest understory. Interestingly, under every eastern hemlock, you find the same small herbaceous plant species. However, you never observe this species anywhere else, even though a healthy diversity of other species live throughout the forest understory. You expect the small herbaceous species to have _____ growth, _____ sexual maturity, _____ energy expended on seeds, and _____ reproduction. Please choose the correct answer from the following choices, and then select the submit answer button. Answer choices fast; early; high; no vegetative slow; late; low; vegetative slow; early; low; vegetative fast; early; low; vegetative slow; late; high; no vegetative

Answers

Answer: slow; late; low; vegetative

Explanation: Due to the casting of deep shade on the forest understory by eastern hemlock, direct sunlight and other necessities for photosynthesis and other life processes needed by the herbaceous plant species for optimum growth is being deprived.

However, coupled with the nature of these herbaceous plant species, having non-woody stems with their growth above the ground level often dieing off particularly in winter in the temperate zone, makes their growth in that kind of location to be stunted.

Thus, herbaceous plant species with slow growth rate leading to late sexual maturuty while having low expanded energy on seeds due to low photosynthetic rate and low vegetative reproduction should be expected.


Farmer Brown notices his tomato plants are leaning towards the front, which results in spoiling tomatoes. Briefly explain to Mr.
Brown what method he can
use prevent that from happening​

Answers

Answer:

Install wood or rebar stakes at least 6 feet-tall at planting time. As the plants grow, tie the stems loosely to the stakes with twine or strips of fabric.The most common cause of leggy seedlings is lack of strong, overhead lighting. Tomato plants become long and spindly when they are reaching for the light. If the light only comes from one direction, then your seedlings not only become leggy, but will also lean towards the light.Generally speaking, in the north, tall plants such as beans, peas, and corn do best on the north side of the garden. Medium size crops such as tomatoes, cabbage, squash, pumpkins, and broccoli in the center of the garden.

1. Blood is at it's highest pressure just when it leaves the heart. Why do you think so?
2. The blood in an artery flows faster and at higher pressure than blood in veins. Why so?

Answers

Answer:

1.Blood pressure can be defined as the pressure of blood on the walls of the arteries as it circulates through the body. Blood pressure is highest as its leaves the heart through the aorta and gradually decreases as it enters smaller and smaller blood vessels (arteries, arterioles, and capillaries).

2. The more rounded the lumen, the less surface area the blood encounters, and the less resistance the vessel offers. Vasoconstriction increases pressure within a vein as it does in an artery, but in veins, the increased pressure increases flow.

True.

Explanation:

Yes, fluids can be liquids or gases depending on the different intensity of the cohesion forces that exists between their molecules because these cohesive forces allows the molecules to attach to one another that leads to their state of matter. Cohesion forces such as hydrogen bonding and van der Waals forces are responsible for the bulk property of liquids that resisting separation from one another so due to these bonding, the molecules attach to one another on the basis of strong bonding between molecules.
