Answer: All living organisms are made up of one or many cells.
Explanation:
In 1830s, botanist Matthias Schleiden studied the tissues individually and proposed the cell theory for the first time. According to him all the living beings are made up of cells and cell is the basic unit of life.
As according to him in the cell division he was able to observe that the plants are made up of cells. This observation is indicating towards the fact that all living organisms are made up of one or many cells.
A student examining an unknown cell under a microscope notes it has a cell wall, cytoplasm, and genetic information contained within a nuclear membrane. Which inference would be correct?
Since the cell possesses a cell wall and genetic information, it has to be an animal cell.
Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.
Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell
Answer:
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic
Explanation:
Since the cell possesses a cell wall and genetic information, it has to be an animal cell.
-this is a plant cell because of the cell wall
Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.
-prokaryotes don't have DNA contained in a nuclear membrane
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.
- DNA contained in a nuclear membrane --> eukaryototic
- cell wall --> plant cells, which are eukaryotic
Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell
-DNA is contained in a membrane should not lead to the conclusion that it's a plant cell, as it could be an animal cell too

You are a scientist and would like to know if a new fertilizer will help plants grow faster. What would the control group be?
A)The group that gets only water, no fertilizer
B)The group that gets water and fertilizer
Answer: The group that gets only water no fertilizer
Explanation:
The control group does not have an additive
The control group will be the group that gets only water, no fertilizer. Thus, option A is correct.
What is function of fertilizer ?
An additional organic or inorganic substances which is added to soil or plants to increase the crop productivity is called as fertilizer.
It contain plant growth promoting nutrients like nitrogen, potassium, and phosphorus; For example, urea, anhydrous ammonia, etc.
The organic fertilizer is derived naturally from plants and animals. It enriches the soil nutrient level, encourage microbial reproduction.
Organic fertilizers are Agricultural Waste, Manure, municipal sludge etc.
Inorganic fertilizers generated chemically contain inorganic nutrients for crop growth; It can be up two types.
Nitrogen fertilizers where nitrogen is the primary element as it is constituent of chlorophyll, maintain the process of photosynthesis, thus improve the crop production.
Phosphorus fertilizer, increases the plant root growth as the protoplasm of the cell contains phosphorus, important for cell growth and proliferation.
Thus, option A is correct.

Sickle cell anemia is a genetic disease that affects the red blood cells. Your red blood cells are typically donut shaped
and have the job of carrying oxygen around your body. In people with sickle cell anemia, the blood cells become
crescent-shaped and are thick and sticky. They are not as able to carry oxygen, and can even get clogged in the blood
vessels blocking the flow of blood, and therefore oxygen to organs, causing pain and organ damage.
Sickle cell is caused by a genetic mutation that changes a single glutamic acid to valine in the 6 th amino acid position.
Examine the codon chart provided above (for #s 3-5), and determine what mutation likely occurred to cause the
change from glutamic acid (GLU) to valine (VAL). To help get you started, it is helpful to know that a person with
NO sickle cell at amino acid #6 has a DNA code of CTC. (4pts)
Normal RNA: ____________, Normal amino acid made: ___________
Mutated RNA: ___________, Mutated amino acid made: ___________

discribe the passive transport movement of a substance down it's concentration gradient through a protein channel embedded in the cell membrane
Answer:
The passive transport of a substance by its concentration gradient through a protein channel is called facilitated diffusion.
Explanation:
Facilitated diffusion is a type of passive transport through the membrane, which involves the use of integral proteins called protein channels or transport proteins, and moves substances unable to cross the membrane by simple diffusion.
An example of facilitated diffusion through protein channels is the ion channel. Ions, being electrically charged particles, cannot pass through the plasma membrane. A protein channel -which crosses the whole thickness of the membrane- constitutes a space where ions can move depending on their concentration gradient.
In facilitated diffusion, both protein channels and transport proteins do not require energy, so it is a transmembrane passive transport process.

an increase in the concentration of protons in the cytosol will most likely have which of the following effects on glycolysis
Answer:
Reaction rate will increase as a result of the increased H+ concentrate
Explanation:
Because the more ions the faster the reaction rate
The increase in the concentration of protons ; increases the Reaction rate
An increase in the number the positive ions ( H⁺ ) in a reaction will lead to an increase the reaction rate and a decrease in the activation energy.
Therefore as the number of protons ( H⁺ ) in the cytosol increases, the ripple effect it will have on glycolysis will be an increase in the rate of reaction ( i.e. Reaction rate ) and a decrease in activation energy.
Hence we can conclude that an increase in the concentration of protons in cytosol will increase the Reaction rate of glycolysis.

Does Soil Affect Flower Color?

By
Mary Simpson
This flower must have grown in neutral soil, with little aluminum.
In some varieties of bigleaf hydrangeas (Hydrangea macrophylla), soil pH determines whether the plant will produce blue or pink flowers. Blooms appear bluest when grown in acidic soil with a pH in the 5.0 to 5.5 range. The same cultivar may sport pink blossoms in soil with a more neutral pH, such as 6.5 to 7.0. Florists control flower color by potting soil mixture

Leukemia is a malignant progressive disease in which the bone marrow and other blood-
forming organs produce increased numbers of immature or abnormal white blood cells.
Which statement about cell cycle checkpoints describes how this disease occurs?
A Dysfunctional checkpoints may lead to abnormal cell growth.
B Defective checkpoints result in death of a cell.
C Normal checkpoints assess damage to cancer cells.
D Cell checkpoints fail only in meiosis.
What would this be.
Answer:
A Dysfunctional checkpoints may lead to abnormal cell growth.
Explanation:
One of the hallmarks of cancer is unregulated cell proliferation. This means cells keep dividing, producing large numbers of often abnormal cells.
There are many of ways this can happen, such as increased signals telling the cells to divide, and dysfunctional cell cycle checkpoints that do not stop the cell from dividing. This leads to the accumulation of mutations and abnormal cell growth.

The eggs of a cone bearing plant:
receive sperm through the development of tubes

Answer:
Cone-bearing plants have two types of cones: female cones and male cones. Reproduction begins when one of the pollen grains from inside a pollen sac on the male cone floats through the air to the scale of a female cone. A pollen tube then grows from the pollen grain toward the female ovule.

Four features of honeybee
Answer:
Bees have 5 eyes.
Bees have been here around 30 million years.
Bees can fly at a speed of 20 miles per hour.
Bees are insects, so they have 6 legs.
An average beehive can hold around 50,000 bees.
Male bees in the hive are called drones.
Female bees in the hive (except the queen) are called worker bees.
Explanation:
Honeybees have black and yellow stripes, a stinger, 5 eyes, and they have 6 legs.
Giraffes are herbivores that initially had shorter necks. They are found in grasslands and areas where trees grow tall. To feed on leaves from tall trees, giraffes had to stretch their necks. This behavior paved the way for
of giraffes with longer necks. A giraffe’s long neck is a
adaptation.
This behavior paved the way for natural selection of giraffes with longer necks. A giraffe’s long neck is a structural adaptation.

Answer:
Explanation:
