Bacteria are classified into five groups according to their basic shapes:
1.spherical shape (cocci) :
e.g Staphylococcus aureus grows best in an aerobic environment but it can also live in anaerobic conditions (without oxygen).
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)

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.
i. Are spindle fibers present during telophase 1?
j. What is happening to the cell membrane in this cell?
Answer:
During telophase I, the homologous chromosomes get segregated into separate nuclei. Although another division must take place for meiosis to be complete, the cells must still reform the nuclear envelopes, disassemble the spindle fiber microtubules, and go through cytokinesis.
What happens during the light dependent
reactions?
Answer:
The light-dependent reactions produce oxygen gas and convert ADP and NADP+ into the carriers ATP and NADPH. ATP and NADPH provide the energy needed to build high-energy sugars from low-energy carbon dioxide.
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
7. Some plants make cones. Other plants make flowers. What is the purpose of flowers and cones?
A. They move water and food throughout the plant.
B. They hold the plant and soil so that it does not blow over in heavy winds.
C. They make seeds so that the plant can reproduce.
D. They take in water and nutrients from the soil.
Answer:
I believe the answer is C.
Explanation:
Coniferous plants (= cone bearing) carry seeds in their cones. This leads me to believe the answer is C because cones do not move water, nutrients, or hold soil.

How does energy transformation happen in photosynthesis
Answer:
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Answer:
It happens because the leaves trap the sunlight energy
Explanation:
When the leaves trap this sunlight energy and combines with the carbon dioxide and water it goes through photosynthesis. This turns the sunlight energy and other resources it collects to energy (sugars) that the plant will use to grow and support itself. It then releases oxygen as a waste which is what humans use. We exhale carbon dioxide that the plants need so while they help us we also help them.

Explanation:
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
Description: Cellular respiration is the process that allows your body to harvest a huge amount of energy from a single glucose. In fact, it's so efficient that you get 30 ATP for every 1 glucose molecule you eat. This exercise is going to break down exactly where each ATP comes from.
Instructions: For this presentation, your goal is to walk the audience through every step that is involved in generating an ATP, NADH or FADH2, include the names, structures and enzyme for each step. From there, look up the conversion rates from NADH and FADH2 to ATP and calculate exactly how 30 ATP are formed. Also include any step which uses an ATP (this will count against the total ATP formed).
What to submit: Please record yourself explaining the structures and enzymes as well as ATP calculation.

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.

Sandra and John have a flock of 4500 sheep, and they started to concern about the wool color after the flock has been closed for random breeding/mating for an extended period. One day, they have counted and found that 950 sheep were white, and the remainders were black. Assume that black wool is controlled by a single locus and the allele for black color is completely dominant to white. Let B represent the black allele and b represent the while allele. Assume HW equilibrium,
A) What is the observed genotypic frequency for the bb genotype?
B) What are the expected gene frequencies for B and b alleles?
C) What are the expected genotypic frequencies and counts for each of the three genotypes?
Answer:
Part A:
Frequency of bb genotype=0.2111
Part B:
Frequency of B alleles is denoted by x=0.5407
Frequency of b alleles is denoted by y=0.4593
Part C:
Frequency of BB genotype=0.2924
Frequency of bb genotype=0.2111
Frequency of Bb genotype=0.4966
Explanation:
Given:
Total Sheep= 4500
White Sheep=950
B for black allele
b for white allele
Part A:
[tex]Frequency\ of\ white\ sheep=\frac{White\ Sheep}{Total\ Sheep}[/tex]
[tex]Frequency\ of\ white\ sheep=\frac{950}{4500}\\Frequency\ of\ white\ sheep=0.211[/tex]
Frequency of white sheep= Frequency of bb genotype=0.2111
Further:
Let frequency of b alleles is denoted by y.
[tex]Frequency\ of\ white\ sheep=y^{2}= 0.211\\y=\sqrt{0.211}\\y=0.4593[/tex]
Frequency of b alleles is 0.4593.
Part B:
Sum of the frequencies of B and b alleles is 1
Let frequency of B alleles is denoted by x
Let frequency of b alleles is denoted by y
x+y=1
y is calculated in part A and has value=0.4593
x+0.4593=1
x=1-0.4593
x=0.5407
Frequency of B alleles is denoted by x=0.5407.
Frequency of b alleles is denoted by y=0.4593.
Part C:
Three genotypes are BB, Bb, bb
In case of three genotypes frequency is:
[tex]F=x^2+2xy+y^2[/tex]
Now [tex]x^2\\[/tex] is for BB genotypes
From Part B;
x=0.5407
[tex]x^2=(0.5407)^2\\x^2=0.2924[/tex](Frequency of BB genotype)
Now [tex]y^2\\[/tex] is for bb genotypes
From Part A:
y=0.4593
[tex]y^2=(0.4593)^2\\y^2=0.211[/tex] (Frequency of bb genotype)
From above frequency Formula:
Now [tex]2xy[/tex] is for Bb genotype:
2*x*y=2*0.5407*0.4593
2*x*y=2*0.2483=0.4966 (Frequency of Bb genotype)
