1.If a population has a birth rate of 0.07 and a death rate of 0.01, calculate the number of individuals added/subtracted from a population of 1,000 individuals in one year. 2.In a mark-recapture experiment, scientists tagged 300 birds in one month. Several months later, they returned and captured 500 birds. 75 of those birds had a tag on them. What is the size of the entire population
Answer:
1. The number of individuals added/subtracted from a population of 1,000 individuals in one year = 70/10 respectively (60 net).
2. The size of the entire population of birds = 2,000.
Explanation:
1. Population = 1,000
Birth rate = 0.07
Death rate = 0.01
Population Growth Rate = Birth rate + Net migration - Death Rate
= 0.07 = 0.01
= 0.06
The number of individuals added to the population = 70 (1,000 * 0.07)
The number of individuals subtracted from the population = 10 (1,000 * 0.01)
Therefore, the overall number added = 60 (70 - 10) or (1,000 * 0.06)
2. Number of birds tagged in one month = 300
Number of birds captured after several months later = 500 birds
Number of birds captured with a tag on them = 75
The proportion of tagged birds out of the captured = 75/500 = 0.15
The size of the entire population of birds = Number of birds tagged/Proportion of captured birds with a tag
= 300/0.15
= 2,000
When Substance Y is applied the cell, the cell functions normally at first, but as time goes on, action potential amplitude gradually decreases, and the resting potential gradually becomes less negative. If the cell is driven to spike more, both of these effects occur more rapidly. What part of the neuron might this substance be affecting/attacking
Answer:
Dendrites.
Explanation:
Dendrites is the part of neuron which is affected by the substance Y which leads to the decrease of action potential because dendrites is the part that obtain information from other cells and carry that information to the cell body of neuron which transfer this information to the neighboring neurons. If the dendrites is damaged or adversely affected due to chemicals then it is unable to perform its function properly and its action potential will be greatly affected.

Parrots can be pink or green. If a parrot is heterozygous, they will always have pink feathers. The allele for pink
feathers must be...
Recessive
Incomplete dominant
Dominant
Co-dominant
Answer:
Dominant
Explanation:
Since there are only two options for the color of the parrot and it is assumed that it can only be one or the other, it cannot be incomplete dominance or co-dominance. And if the heterozygous parrot, which is Xx, is pink then the allele specifying the pink color must be dominant

Name one trait that can help a plant survive in the desert.
Answer:
If they have a source of generating water like a cactus
Explanation:
Answer:
Hope this helps
Explanation:
Smaller Leaves and Stems
One of the chief adaptions of plant life to desert climates has been to reduce leaf and stem size. This allows the plant to concentrate its water instead of spreading it out over a wider surface area. Desert trees and shrubs tend to be short, with fewer leaves and branches. The most extreme form of this adaptation is found in the cacti, whose stems and leaves have been reduced so much that only spines remain. These spines also can shade the plant, helping it conserve even more moisture. With cacti, the primary photosynthetic activity has been moved to the stalk, the main body of the plant, and away from the leaves.
Storing Water
Some plants in the desert have developed the ability to store water. Desert plants with thick leaves and stems are able to absorb water when it rains and continue growing even when rainfall is absent. Some desert plants have developed holding sacks in their stems that swell to hold water during those times when it is available. Some types of cactus have this ability, as do black sage and rice grass.
Dormant Periods
Other plants have learned to go dormant when water is scarce. This conserves their resources during times of hardship. When water again becomes available, these plants wake up and resume growing. Desert plants with dormant phases include lichen, moss, algae and ferns.
Nocturnal Activity
Some desert plants survive by only becoming fully active at night. During the night time, evaporation is least likely to occur because it is no longer so hot. Some plants, such as the yucca, turpentine bush, and brittlebush, only open their stomas at this time. Stomas are microscopic openings in the “skin” of the plant that allow it to breathe. By only exposing their mist insides to the outside air at night, they lose less moisture.

Why the surface of motor end plate of skeletal muscle are NOT smooth?
Answer:
The axons that innervate smooth muscle fibers do not have typical branching end feet of the type in the motor end plate on skeletal muscle fibers. ... In the varicosities are vesi-cles similar to those in the skeletal muscle end plate that contain transmitter substance.
Explanation:
Hey mate, here's your answer...
The motor end plate is the neuromuscular junction present at the muscle fibers. The plates of the smooth muscles are not smooth as they contain terminal branches of the nerve axons.
What are motor end plates?Motor end plates are neuromuscular junctions that are chemical synapses formed at the site where the terminal branch of the nerve axons lies and is in contact with the skeletal muscle cells.
The skeletal muscles have the motor end plate, which is an essential synaptic contact created between the axons of the motor nerve cells and the skeletal muscle fiber.
These neuromuscular junctions are important connections that are involved in the transportation of the electrical impulses and signals to make the skeletal muscles contract.
Therefore, the motor end plate of the skeletal muscles is not smooth.

Explanation:
The majority of cells in a human body go through mitosis and not meiosis. Is this true or false?
Answer:
True
Explanation:
Mitosis results in two cells that are genetically identical. DNA replication only occurs during "S phase." Meiosis is commonly defined as a type of cell division that divides a somatic cell and produces four gamete cells when doing so.
S phase: In S phase, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase.
Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.
This statement is true.
What do you mean by mitosis and meiosis?Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
Moreover, mitosis is a process where a single cell divides into two identical daughter cells (cell division). Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.
Therefore, daughter cells resulting from mitosis are diploid, while those resulting from meiosis are haploid. Daughter cells that are the product of mitosis are genetically identical. Daughter cells produced after meiosis are genetically diverse. Tetrad formation occurs in meiosis but not mitosis.

2.rod shape (bacilli):
3. spiral (spirilla) :
4.comma (vibrios) or corkscrew (spirochaetes):
They can exist as single cells, in pairs, chains or clusters.
Microorganisms can be classified according to their oxygen requirements necessary for growth and survival:
Obligate Aerobes: (oxygen required)
Facultative: (grow in the presence or absence of oxygen)
Microaerophilic: (grow best at very low levels of oxygen)
Aerotolerant Anaerobes: (oxygen not required for growth but not harmful if present)
Obligate Anaerobes: ( grow only in complete absence of oxygen; if present it can be lethal)
