Answer:
The bird populations will decrease due to competition for resources such as food and nesting sites.
Explanation:
Ecological succession can be defined as the process by which the biological structure of a community, i.e., the group of interacting populations of species that occupy a particular area, changes over time. Human activities such as, for example, deforestation in order to develop an urban ecosystem, can dramatically alter the process of succession and literally destroy the natural balance of biological communities. In this case, it is expected that human activities have a negative impact on bird populations by increasing intra and interspecific competence with other organisms for limited resources (i.e., food and nesting sites).

how does the ribosome read the mRNA?
Answer:
A ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on the mRNA, codon by codon, as it is read and translated into a polypeptide (protein chain).

9. Which nucleus has role in conjugation in Paramecium
a) Mega nucleus
b) Micronucleus
c) Macronucleus
d) Cellular nucleus
( b ) Micronucleus has role in conjugation in paramecium.
The organism's germ line genetic material is kept in the micronucleus. It is in charge of the genetic rearrangement that takes place during conjugation and generates the macronucleus (cross-fertilization). Thus option B is correct.
What Micronucleus role in conjugation in Paramecium?The pairing and subsequent fusion of two paramecia is a process known as conjugation. It is known as a cytoplasmic bridge where they converge. After meiosis, the diploid micronucleus divides into four new micronuclei. The micronuclei of the cell, all except one, break down.
This method doesn't include meiosis or nuclear fusion. It manifests in a single person in the manner described below: Macronucleus deteriorates and vanishes. Eight nuclei are produced after the two micronuclei divide twice through mitosis.
Therefore, Micronucleus has a role in conjugation in Paramecium.

Explanation:
In people-eaters, purple is dominant to white. A true-breeding white mutant is mated with a different true-breeding white mutant. All of the F1 are purple. When the purple F1 offspring mate with each other, their offspring occur in the ratio of 9 purple : 7 white. Which phenomenon explains the purple F1 offspring
Answer:
The correct answer is - Complementation.
Explanation:
In this pattern of inheritance, there are two same type mutants that are crossed that are true-breeding white with another true-breeding white mutant. Let these mutants are CCpp and the other be ccPP.
All the f1 offspring produced are found to be purple in color as offspring will be CcPp. The products of both gene C and P required for the purple pigment to be expressed these genes complement each other and the absence of any of gene results in lack of the dominant phenotype.
Which of the following occurs first in meiosis?
1. Homologous chromosomes line up in the center of the cell.
2. Chromosomes line up in the middle of each cell.
3. Crossing over between segments of homologous chromosomes.

Answer:
Crossing over between segments of homologous chromosomes.
Explanation:
Crossing over happens during prophase I of meiosis I
What is biomass burned to produce
Answer:
Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas. However, the plants that are the source of biomass for energy capture almost the same amount of CO2 through photosynthesis while growing as is released when biomass is burned, which can make biomass a carbon-neutral energy source.
:)))))))))help me plsss
Explanation:
1. The materials are physically combined because all of the materials including the sand, salt, and iron fillings are their own substances and they maintain their original form. This is a mixture and they aren't chemically combined.
2. To separate each of the materials physical means would be used because since they're their own individual substances and have kept their original form they're mixed and not chemically combined.
3. The iron and oxygen atoms in rust are chemically combined because they are no longer individual substances and haven't kept their original form, so therefore they're a chemical combination.

Which factors affect the gravitational force between two objects?
Answer: The size of each object and the space between them.
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
It is estimated that the world human population reached 3 billion people in 1959 and 6 billion in 1999. Assuming a carrying capacity of 16 billion humans, write and solve the differential equation for Gompertz growth, and determine what year the population reached 7 billion. Was logistic growth or Gompertz growth more accurate, considering world population reached 7 billion on October 31,2011
Answer:
i ) Gompertz equation :
[tex]\frac{dP(t)}{dt} = \alpha In ( \frac{K}{P(t)} )P(t)[/tex]
ii) The year that population reaches 7 billion is 2013
iii) The logistic growth was more accurate
Explanation:
i) write and solve the differential equation for Gompertz growth
Gompertz equation :
[tex]\frac{dP(t)}{dt} = \alpha In ( \frac{K}{P(t)} )P(t)[/tex]
∝ = growth rate
k ( carrying capacity ) = 16 * 10^9
P(t) = population at time t
ii) Determine what year the population reached 7 billion
The year that population reaches 7 billion is 2013
solution attached below
iii) Determine if logistic growth or Gompertz growth was more accurate considering world population reached 7 billion on October 31,2011
The logistic growth was more accurate because the when Logistic growth model was used, the year in which the population reached 7 billion was 2010 and this value is more closer to 7 billion on October 31 2011 ( given value )

The promoter is the binding site for RNA polymerase, the enzyme that performs transcription.
Explanation:
The operator is a negative regulatory site bound by the lac repressor protein. The operator overlaps with the promoter, and when the lac repressor is bound, RNA polymerase cannot bind to the promoter and start transcription.

A woman and her baby are on a TV talk show to determine whether or not a particular man is the father of the child. Mom is blood type O and the baby is blood type B. The potential dad is blood type A. Is it true or false that he is the father?
Answer:
No that is not the father
Explanation:
The fathers blood would have to be type B. Type A is dominate to O and co-dominate to B so you get AB blood, type B blood is dominate to O blood. So if the mom has to be OO to show O blood and the father has to be AA blood because he isn't AB or AO, which could make the baby AO or OO blood. Since none of this is true the "TRUE" father would have to have AB, BB, or Bo blood.
Each fragment generated during the cycle sequence reaction is labeled with:
A. All four colors of fluorescent dye throughout the length of the fragment
B. All four colors of fluorescent dyes at one end of the fragment
C. One color of fluorescent dye at one end of the fragment
D. One color of fluorescent dye throughout the length of the fragment
Answer:
C
Explanation:
In cycle sequencing technique, four distinctive fluorescently named dideoxyNTPs are utilized ( ddATP, ddGTP, ddCTP and ddTTP) notwithstanding ordinary dNTPs. each ddNTP marked with an alternate fluorescent color. Toward the finish of the experiment, the outcome yields various pieces of variable lengths each resulting in a solitary terminal fluorescent ddNTP towards the end.
