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
Activity B: Mechanical and chemical digestion Get the Gizmo ready: Click Reset and Clear screen. Build a system with a Mouth, Salivary gland, Esophagus, Pancreas, and Rectum. Introduction: Before nutrients are absorbed, they must be broken down to their simplest components. Teeth and muscular contractions in the stomach break food down into smaller particles, a process called mechanical digestion. In the meantime, powerful chemicals break down food in a process called chemical digestion. Question: How are nutrients broken down in your digestive system

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.
Al the following are parts of the cell theory except-
All cell function in unique ways.
All living things are composed of cells.
Cells are the basic units of structure and function in living things.
All cells are produced from other cells.
Other:
Answer:
All cells are made from the same major classes of organic molecules: nucleic acids, proteins, carbohydrates, and lipids, They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function.
Explanation:
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.

Please need help with this biology question (photo)
Answer:
Energy flows through the organisms from bottom to top and increases at each level.
Explanation:
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.
Description: For the video response portion of this assignment, your job will be to calculate the amount of ATP produced anaerobically using the logic of the person’s presentation you watched. Discuss whether or not you agree with this.
Answer:
The complete glycolysis and citric acid cycle pathway is shown in diagram.
# Reactions of glycolysis that –
I. Consumes ATP = 1, 3
II. Produces ATP = 7, 10
III. Consumes NAD+ and produces NADH = 6
IV. Consumes FAD and produces FADH2 = none
# Reactions of TCA that –
I. Consumes ATP = none
II. Produces ATP = 6
III. Consumes NAD+ and produces NADH = 4, 5, 9
IV. Consumes FAD and produces FADH2 = 7

Extra-large breakers are crashing into the surf. How will this affect the undertow? Make a prediction
Answer:
This will make the undertow return to the sea with greater intensity and violence.
Explanation:
Undertow is the movement of the wave in contrast to the sea, that is, it is the movement of the waves on themselves, which makes the sea very agitated, especially when these waves return to the sea with a lot of violence and force. Although this violence and force can be caused by the wind, extra-large breakers can also cause this effect, because the impact of the waves on the breakers, pushes the waves into the sea with more force, making them more violent and intense.

Answer:
sir sorry
Explanation:
Typically, acetylation of histone tails leads to ________. Typically, acetylation of histone tails leads to ________. relaxed packaging of the chromatin and increased transcription activation of topoisomerase removal of the protein components of the chromatin from the DNA tighter packaging of the chromatin and reduced transcription increased amounts of euchromatin relative to heterochromatin
Answer:
relaxed packaging of the chromatin and increased transcription.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and are responsible for condensing it to chromatin.
Typically, acetylation of histone tails leads to relaxed packaging of the chromatin and increased transcription.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

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)
.
