Answer:
Decrease in number.
Explanation:
Decrease in number is the evidence that shows that the populations of paramecia affect each other because the food is limited in the environment and the paramecia species compete for the food source. During this competition, the population of paramecia decreases and only those species survive which avail the food while the remaining will die due to unavailability of food.

1. Which of the following statements about telomeres is
incorrect?
a) They function like a counter, keeping track of how many
times a cell has divided.
b) At birth, they are long enough to permit approximately
50 cell divisions in most celk.
c) They are slightly shorter in prokaryotic cells than in
eukaryotic cells.
d) They function like a protective cap on chromosomes
e) They contain no critical genes.
The statement 'telomeres are slightly shorter in prokaryotic cells than in eukaryotic cells' is INCORRECT (Option C).
Telomeres are DNA sequences localized at the ends of eukaryotic (linear) chromosomes.
These DNA sequences (telomeres) are composed of nucleotide tandem repeats.
Most prokaryotes (e.g., bacteria) have circular genomes and therefore they do not have telomeres.
In conclusion, the statement 'telomeres are slightly shorter in prokaryotic cells than in eukaryotic cells' is INCORRECT (Option C).

The molecular attraction of a substance never changes.
True or False?
Molecular attraction for a substance remains same thus, statement is true.
What is molecule?When one or more atoms are held together to form a group, with help of chemical bonds which are nothing but attractive forces, referred to as molecules.
Molecules as elements of matter and are common. They also make up most of the oceans and atmosphere. Most organic substances are molecules. The substances of life are molecules, e.g. proteins, the amino acids of which they are composed, the nucleic acids (DNA and RNA), carbohydrates, fats, and vitamins. The nutrient minerals are generally ionic compounds, thus they are not molecules.
Different substances have different levels of attraction, but the level of molecular attraction for any one substance is always the same. Therefore, the statement is true.

Evaluate the pros and cons of using an NPK fertilizer, a natural compost, and lime on a field with substantial amounts of clay and humus and with a low pH of 3, which is to be planted with a legume crop.
Answer:
Leaching of nutrients occur.
Explanation:
NPK fertilizers are applied to the field all over the world because it has a good effect on the growth and development of plants but it has also some environmental effects such as leaching which pollutes water bodies whereas natural compost is good for the plants as well as for the soil organisms but its breakdown is very slow and it is not readily available to the plants. Lime is also very good for the soil having low pH because lime is basic in nature and it increases the pH of the soil.

The term dominant generation refers to
Answer:
The dominant generation is haploid, so that the gametophyte comprises what we think of as the main plant. The opposite is true for tracheophytes (vascular plants), in which the diploid generation is dominant and the sporophyte comprises the main plant.
The term dominant generation refers with respect to plant classification and characteristics.
What do you mean by Dominant?Dominant is something that masks the effect of others in the same condition.
In Bryophyta (non-vascular plants), the dominant generation is haploid (n), so the gametophyte consists of the main plant. The opposite is observed for Tracheophyta (vascular plants), in which the diploid (2n) generation is dominant and the sporophyte consists of the main plant.
Therefore, the term dominant generation refers with respect to plant classification and characteristics specifically.

which organelle does the skeletal system connect to and why?
Answer:
Muscles connect to your skeleton and they contract and move the skeleton along. Your skeletal system is made up of cartilage and calcified bone that work together. They help the process of movement happen in a smoother manner. The calcified bones of your skeleton also work with the circulatory system.
Answer:
Organelles of a skeletal muscle cell contain the same organelles as other animal cells, with the addition of myofibrils. Muscle fibers within the skeletal cell are known as myofibers. These organelles allow skeletal muscle cells to contract. Skeletal muscle cells do contain more mitochondria than other cells, because muscle cells require more energy and must convert more glucose. Skeletal muscle cells also differ from other cells because of the myofilaments within the myofibrils. Within these filaments are proteins known as myosin and actin. The special filaments enable the skeletal muscles to contract. The myofibrils within skeletal muscle cells are divided into units known as sarcomeres, which are the units of skeletal muscle cell contraction.

Birth rate = 35
Death rate = 7
Immigration = 4
Emigration = 17
What is this population growth?
population increases by 41
population decreases by 15
population increases by 15
population decreases by 24
Answer: population increases by 15
Explanation:
The population growth will be calculated by adding the Natural Increase in population plus the Net In-Migration. This will be:
Natural increase = Birth - Death rate
= 35 - 7
= 28
Net-In-Migration = Immigration - Emigration
= 4 - 17
= -13
Therefore, population growth will be:
= 28 - 13
= 15
Therefore, population increases by 15
In the given case, the population growth - population increases by 15
Population growthPopulation growth is the increase in the number of people in a population or the change in the number of individuals of a species in an area over time.It can be calculated by the difference between the addition of individuals and the removal of individuals from the populationAddition can be by immigration or birth whereas removal can be emigration or deathSo growth = (birth rate + immigration) - (death rate + emigration)
Then, population growth = (35+4) - (7+17)
= 39 - 24
= 15
Thus, In the given case, the population growth - population increases by 15

Look at the albino whale people have named Migaloo. The white color is the result of mutations in the genes that code for the proteins responsible for skin color. Is Migaloo’s white color likely to be an advantage in its current environment? Explain your answer.
No, the white color of Migaloo is not most likely an advantage in its current environment. This is because white is the color that is easily perceived by predators.
What is the Mutation?A mutation may be defined as sudden, stable, and inheritable changes in the genetic material of an organism. An organism that undergoes an event of mutation is known as a Mutant. The agents of mutation are known as mutagens.
White color is easily perceived by predators as compared to black, brown, grey, etc. So, it somehow reduces the fitness and survivability of Migaloo. This white color is the result of mutations in the genes that code for the proteins responsible for skin color.
Therefore, the white color of Migaloo is not most likely an advantage in its current environment.
