name the various classes of algae given by F E Fritsch
Answer:
1. Chlorophyceae
2. Xanthophyceae
3. Chrysophyceae
4. Bacillariophyceae
5. Cryptophyceae
6. Dinophyceae
7. Chloromonadineae
8. Euglenineae
9. Phaeophyceae
10. Rhodophyceae
11. Cyanophyceae or Myxophyceae.
Explanation:
Algae are a group of living organisms classified under the kingdom Protista. They exhibit unique characteristics such as mode of reproduction, type of pigment, food reserve material, locomotive ability etc.
A british scientist (botanist) named Felix Eugen Fritsch in 1935 classified algae into 11 different classes based on some of these characteristics. The classes of algae are as follows:
1. Chlorophyceae (green algae)
2. Xanthophyceae (yellow green algae)
3. Chrysophyceae
4. Bacillariophyceae (diatoms)
5. Cryptophyceae
6. Dinophyceae
7. Chloromonadineae
8. Euglenineae
9. Phaeophyceae (brown algae)
10. Rhodophyceae (red algae)
11. Cyanophyceae/Myxophyceae (blue green algae)
Which factor plays a central role in determining which of the brain's synapses will be eliminated and which will be maintained?
Answer:
The answer is "frequency with which they are activated".
Explanation:
Frequency refers to the number of consecutive repetitive events per unit time. It is measured in hertz (Hz), equivalent to a single event per second. The time is the number of one cycle in a recurrent event, and so the duration is the same for the frequency, hence the frequency at which they are triggered is a key determinant of the brain's connections to be eliminated and maintained.

What is a variegated leaf
Answer:
The term, "variegated" is applied to a flower or, more often, a leaf that has more than one color. Most often, it will be two-toned (that is, bi-colored). Often this will mean the foliage is blotched, striped, or bordered with a lighter color than that on the rest of it (or vice versa). The term is also applied more broadly to a whole plant that bears such leaves or blossoms. The corresponding noun for this definition is "variegation."
A population of rabbits has individuals with fur coloring that ranges from white to brown. The population lives in a temperate deciduous forest where the summers are mild and average about 50°F. The winters are often below freezing.
If warmer temperatures last longer into the fall and the average temperature in the winter is getting warmer, what do you expect to happen to the population?
The percentage of the population with brown fur will decrease.
The percentage of the population with white fur will decrease.
The population will increase in size, but the color percentages will remain unchanged.
The population will decrease in size, but the color percentages will remain unchanged.
Answer:
The best option for this problem would be the second option: "The percentage of the population with white fur will decrease"
Explanation:
Think about animals up in the north. Most of them are white because it helps them blend in the snow. And so an increase in average temperatures would mean less snow time. This would mean that the white rabbits will be more vulnerable to attacks for a longer time period of the year compared to previous years with a short time period of being vulnerable.

The pharynx is the structure in the body that serves as a pathway of both air and food. How does the body make sure that food does not get into the lungs?
Answer: The body makes sure that food does not get into the lungs because the epiglottis closes the air pathway so that food will not enter it.
Answer:
food getting to the lungs will be aspiration
Explanation:
A flap of tissue called the epiglottis sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow hence preventing food from getting into the lungs

Asexual reproduction differs from sexual reproduction in that Group of answer choices asexual reproduction utilizes DNA from two parents to code for traits in offspring. asexual reproduction occurs only in plants. asexual reproduction produces offspring containing DNA from only one parent. asexual reproduction only occurs in animals. asexual reproduction produces genetically diverse offspring.
Answer:
Asexual reproduction produces offspring containing DNA from only one parent.
Explanation:
Asexual reproduction produces offspring containing DNA from only one parent because in asexual reproduction, the organisms born or produced from a single parent. The offspring is identical to their parent and this process of asexual reproduction occurs in both plants and animals. Asexual reproduction produces identical not genetically diverse offspring in the end of the process.
Answer:
Because asexual reproduction results in the birth or creation of organisms from a single parent, the children created have DNA from just one parent. Both plants and animals can reproduce asexually, and the progeny are identical to their parents. Asexual reproduction ultimately results in identical, not genetically different, offspring.

Describe the thickness of the uterus lining during
menstruation process.
Answer:
As the cycle progresses and moves towards ovulation, the endometrium grows thicker, up to about 11 mm. About 14 days into a person's cycle, hormones trigger the release of an egg. During this secretory phase, endometrial thickness is at its greatest and can reach 16 mm.
Explanation:
Answer:
During this timeframe, the uterus is in the proliferative phase. Estrogen induces growth of the functional layer of the endometrial lining, which enables it to grow from about 1-3 mm post cycle to 6-8 mm approximately. Days 12-16 of the menstrual cycle At this point, the endometrial layer is about 6-8 mm thick.

One student made the incomplete diagram shown below to represent the relationship between magma igneous rocks and metamorphic rocks.
Which of these is the correct next step to complete the diagram?
A. Put an arrow labeled cools and crystallizes pointing from igneous rocks to metamorphic rocks
B. Put an arrow labeled cools and crystallizes pointing for metamorphic rocks to igneous rocks
C. Put an arrow labeled heat and pressure points in from igneous rocks to metamorphic rocks
D. Put an arrow labeled heat and pressure pointing from metamorphic rocks to igneous rocks
Answer:
C. Put an arrow labeled heat and pressure pointing from igneous rocks to metamorphic rocks
Explanation:
Metamorphic rocks are changed rocks that are formed from pre-existing rocks that were once sedimentary or igneous rocks. Heat and pressure majorly act on igneous rock, which over time change these rocks into a different rock entirely, known as metamorphic rocks.
Therefore, the next step to complete the diagram will be:
"C. Put an arrow labeled heat and pressure pointing from igneous rocks to metamorphic rocks."

which type of hormone diffuses across the plasma membrane and binds to receptors in the cytoplasm module 16.4c
Answer:
Steroid hormones.
Explanation:
Steroid hormones is a type of hormones that diffuses across the plasma membrane and binds to the receptors present in the cytoplasm. The hormones are released from the carrier protein and diffuse inside the cell across the lipid bilayer of the plasma membrane of the cells. The steroid hormones pass through the plasma membrane of a target cell and attached to the intracellular receptors located in the cytoplasm or in the nucleus.

Which type of selection is also known as diversifying selection because it tends to favor the survival of two or more different phenotypes in a heterogeneous environment
Answer:
Disruptive selection.
Explanation:
Disruptive selection is also called diversifying selection because it favor the survival of two or more different types of phenotypes in a particular environment. Disruptive selection describes changes in population in which extreme values for a trait are favored whereas the intermediate values are less favored. Due to the increase the variance of the trait which leads to the division of population into two distinct groups.

What is a technique that aims to reduce viable spoilage microorganisms so they are unlikely to cause disease?
Answer:
Pasteurization
Explanation:
Food products such as milk, wine and beverages may be subjected or placed on a heat treatment process with the aim of reducing active microorganisms present in them. This will improve the quality of food materials and also prolong its life span. This heat treatment process help destroy pathogenic microorganisms and those which are responsible for food spoilage. Once this food spoilage microorganisms are destroyed, the good products will have enhanced or prolonged life span of the food product and also reduces their risk of causing disease.
