Why do Primary succession happen
Answers
Answer:
Explanation: Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time. For example, primary succession may take place following the eruption of volcanoes, such as those on the Big Island of Hawaii. As lava flows into the ocean, new rock is formed.

A student is investigating gas production of water plants of various sizes. She predicts that larger plants produce more oxygen. She places a test tube and funnel upside down over a water plant submerged in water. The test tube collects gas the plant produces when in sunlight. A diagram of her setup is shown below.
In this experiment, what is the independent variable?
A.The number of gas bubbles
B. The varying size of the plants
C. The test tube used to collect gas
D. The temperature of water in the beaker
Answers
Answer: The test tube used to collect gas (C)
Explanation: If you illuminate a plant (I presume you are using an aquatic/water plant) it will produce oxygen. You can put the plant under a funnel and collect the bubbles in an upturned test tube. If the gas is collected fresh, it will relight a glowing splint. However, if the gas takes more than 24 hours to collect, or if you leave it for several hours before testing it, you may not relight a glowing splint.

A spring toy is moving down steps, What happens to the energy of the toy?
A. The toy gains energy as it moves.
B. The toy loses energy to the steps.
C.The amount and type of energy of the toy stays the same.
D. The amount of energy the toy has stays the same, but it changes form.
Answers
Answer:
Option (d) is correct.
Explanation:
When a spring toy is at the maximum point, it have maximum potential energy because it is given by :
PE = mgh where h is height and g is acceleration due to gravity
When it moves down steps, its potential energy decreases and kinetic energy increases and it is given by :
KE=1/2 mv^2 where v is velocity of the object
It means when it is moves down step, the potential energy gets converted to kinetic energy. So, the amount of energy the toy has stays the same, but it changes form. Hence, the correct option is (d).
A certain wastewater treatment plant uses aerobic bacteria, anaerobic bacteria and archaebacteria during secondary treatment of sewage. Unfortunately, during a bad bluzard the sludge digester froze, killing the microbes inside. What is likely to result? a) Floc levels will diminish b) Solid material will not be effectively fitered out c) Methane production will go down d) Floc will not be effectivelyftered out
Answers
Answer:
The correct option is C
Explanation:
Anaerobic bacteria used in sewage treatment helps to reduce the volume/amount of sludge in the sewage thereby producing methane gas from it. Some companies produce there own (not for sale) methane gas (as an alternate source of energy) through this process. Thus, a decrease in the amount of this bacteria (perhaps through death as described in the question) will lead to a decreased production of methane gas.

Identify the organelles in the cell. Label A Label B Label C Label D
Answers
Answer:
This question is incomplete
Explanation:
This question is incomplete but the completed/similar question with the diagram is in the attachment below.
First of all, the cell is a plant cell because of the presence of the large central vacuole present and also the green colour of the outer part of the cell (which is not a coincidence). Let's proceed to identifying the organelles.
Label A is the large central vacuole. This is not the nucleus as might be confused with because the nucleus is the next big reddish organelle to the right of the vacuole.
Label B is the cell wall. Because this is a plant cell, it has a cell wall which can be clearly seen to be the most outermost layer. While the next yellow boundary line is the plasma membrane.
Label C is the chloroplast. Recall from elementary biology that the chloroplast stores the green pigment chlorophyll. The green colour of this internal organelle makes it identifiable as the chloroplast.
Label D is the starch granule. The shiny semicrystalline structure of this organelle makes it identifiable as the starch granule.
Answer:
Chloroplast, Vacuole, Cell wall, Endoplasmic reticulum
Explanation:
Label A: Chloroplast
Label B: Vacuole
Label C: Cell wall
Label D: Endoplasmic reticulum

What are two tools used for sending information? cars and buses water and wind smoke and wood radio waves and lightwaves
Answers
Answer:
radio waves and lightwaves
Explanation:
Radio waves and light waves are both types of electromagnetic waves in the electromagnetic spectrum. Radio waves and light waves travel a particular distance and hence, are used to convey information over distances.
Based on this question, radiowaves and light waves are both tools used to send information. Radiowaves carry information from the station to the receiver, likewise light waves from one medium to another.
Examine a two-gene cross in which a mutation in HERC2 is epistatic to the OCA2 gene. In a cross between a blue-eyed OOhh woman and a blue-eyed ooHH man, what eye color will the progeny have?
a. 9 brown eyes: 7 blue eyes
b. 3 brown eyes: 1 blue eyes
c. All blue eyes
d. All brown eyes
Answers
In recessive epistasis, the epistatic gene -HERC2- in h0m0zyg0us recessive state inhibits the expression of the hypostatic gene -OCA2-. In the example, the F1 is heter0zyg0us for both genes. Option D. All brown eyes.
Epistasis
When talking about epistasis, we are referring to an interruption.
These are interactions between genes located in different loci in the same chromosome.
An epistatic gene can alter, influence, or suppress the expression of a hypostatic gene.
When the epistatic gene is recessive, the interaction is known as recessive epistasis.
Available data:Two genesHERC2 gene is epistatic to the OCA2 geneCross: blue-eyed OOhh woman and a blue-eyed ooHH manWe will assume that
H allele expresses colorh allele inhibits colorO allele expresses browno allele expresses blue.Genotypes Phenotypes
HHOO, HhOO, HHOo, HhOo Brown eyes
HHoo, Hhoo Blue eyes
hhOO, hhOo, hhoo Blue eyes
Individuals that are h0m0zyg0us recessive for HERC2 have blue eyes regardless of the genotype of the OCA2 gene.
This is, the genotype hh inhibits the expression of OO, Oo and oo.
Cross:
Parentals) OOhh x ooHH
Gametes) Oh, Oh, Oh, Oh

Punnett square) Oh Oh Oh Oh
oH OoHh OoHh OoHh OoHh
oH OoHh OoHh OoHh OoHh
oH OoHh OoHh OoHh OoHh
oH OoHh OoHh OoHh OoHh
F1) 100% of the progeny will be heter0zyg0us for both genes, expressing brown eye color.
Among the progeny, neither of the genes is in h0m0zyg0us recessive estate, meaning that the expression of brown eyes is possible.
The eye color among the progeny is expected to be 100% brown eyes. Option D.

The lac operon is regulated by both the availability of lactose and glucose. How does E. coli regulate transcription of the lac operon?
Answers
Answer:
E. coli regulate transcription of the lac Operon through the production of a small molecule called cyclic AMP (cAMP).
Explanation:
The lac operon is regulated by both the availability of lactose and glucose. E. coli regulate transcription of the lac Operon through the production of a small molecule called cyclic AMP (cAMP).
This cAMP acts a signaling agent which is made by E. coli anytime glucose levels are low In the cells which helps regulate the transcription process as glucose is needed for it .
What experiment conducted by andre jagendorf with isolated thylakoid membranes proved that possibles solutions?A. Blue and red light, but not green, caused photosynthetic production of oxygenB. The ATP synthase complex functioned as a molecular rotary engineC. Molecular oxygen (O2) is derived from water, not CO2D. ATP and NADPH are the direct products of the light reactions, not sugar.E. ATP synthesis could be energized by a proton gradient.
Answers
Answer:
The correct answer is option E, that is, synthesis of ATP could be mediated by a proton gradient.
Explanation:
Andre Jagendorf inserted chloroplasts for many hours within a buffer of pH 4 and then instantaneously mixed that with the buffer of pH 8. He came to known that in the stroma, a change in pH was witnessed, that is, it moved to 8 while in the thylakoid space there was no change, that is, the pH remained at 4. He then isolated the thylakoid and put it in the dark, he noticed that it produced ATP. This proves the hypothesis of Peter Mitchell that the production of ATP is mediated by proton-motive force.
