Answer:
Colonization by plants may provide habitat, facilitating colonization of animal species.
Early colonizing plants may increase the nutrient level of the soil, facilitating the colonization of other plant species.
Animal colonizers may increase pollination of some plant species, facilitating their colonization.
Explanation:
The plants provides habitat as well as food to organisms that helps in the colonization of that organisms because every organism needs food and living place for its survival. Some plants increase the nutrient level in the soil through fixation of nitrogen which leads to the colonization of other plant species in that environment. Some animals causes pollination of plants which helps them in their colonization so all these organisms have a positive impact on the occurrence of other species.

Which of the following is not a abiotic factor ?
A. Dirt
B. Sunlight
C. Water
D. Air
Answer:
A) Dirt
Explanation:
Our environment comprises of two factors namely biotic factors and abiotic factors. Biotic factors are those in an ecosystem that consists of all living organisms such as plants, trees, humans, insects, animals, birds, etc. These living organisms will interact with each other and sustain their life.
Abiotic factors are those that contain non-living organisms. These factors include soil, air, water, sunlight, etc. These factors often have a greater impact on biotic factors. From the question, a plant is a living thing and it belongs to the biotic factor.
Answer: They are all Abiotic factors actually but my best guess would be B. sunlight

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.

A forest area is belag used for a new housing development. Most of the trees have been removed to make room for
the new houses, Predict the impact that this will have on the birds in the area.
The bird populations will stay the same because humans love birds,
The bird populations will decrease because humans see them as pests.
y The bird populations will increase because humans do not interfere with wild animals.
The bird populations will decrease due to competition for resources such as food and nesting sites.
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).

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.
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.

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.
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.

Answer:
it says that plants are the main source of nutrients and energetic materials and when the cow feed on them, it consumes some of the benefits that we miss when we eat beef
Answer:
Question 6: The answer is the energy, because it collects more energy than the cow. When the cow eats plants, the energy from the plant decreases leaving the cow with only little amount.
Question 7: I agree, Because plants holds way more nutrients and energy than meat. I could support that by saying when a herbivore eats from a plant, It only recieves 10%.

Which of the following correctly states how genes, chromosomes and traits are related? A Chromosomes are part of genes. The traits determine our chromosomes. B Traits are segments of chromosomes. The chromosomes make up our genes. C Genes are segments of DNA on chromosomes. The genes code for proteins that make our traits. D Chromosome are make up of DNA which is divided into genes. The traits are all of the chromosomes we find in a cell.
Answer:
C
Explanation:
While D could be the right answer if it was phrased better the most liekly answer seems to be C as Genes are small segments of DNA and DNA makes up chromosomes in turn causing chromosomes to be made up of genes. I believe that proteins do make our traits so C is the best answer.
Genes are segments of DNA on chromosomes. The genes code for proteins that make our traits. So, the correct option is (C).
What are Genes?Genes are defined as the basic units of heredity passed from parent to child that are made up of sequences of DNA and arranged one after the other at specific locations on chromosomes in the nucleus of cells.
Genes are found in each one of the 37 trillion cells that make up the body. Every cell has a nucleus and inside each nucleus are chromosomes and all chromosomes are made of DNA, molecules that contain genetic information called genes.
A chromosome contains hundreds to thousands of genes where each normal human cell has 23 pairs of chromosomes, for a total of 46 chromosomes. Trait is any gene-determined characteristic and is often determined by more than one gene.
Thus, Genes are segments of DNA on chromosomes. The genes code for proteins that make our traits. So, the correct option is (C).

Why do large islands usually have more species than smaller islands?
Answer: Reason Why
Explanation: A bigger target is easier to hit than a small one, and a big island is more likely to have species land on it by chance than a small one is. Larger islands have more space than smaller islands, so there are likely to be more resources available for species to use. The opposite is true for smaller islands.
