strobila or cone produce egg cell in non flowering plants
The organ in many nonflowering plants which produces an egg cell is the strobila or cone produce.
What is nonflowering plants?Nonflowering plants don't produce flowers; instead, they produce microscopic reproductive elements called seeds or spores that may be used to create additional plants that look just like them.
What is strobila?A shorter stem with several altered leaves bearing sporangia makes up strobili. Gymnosperms, like all seed plants, are heterosporous. Usually, different cones are used to carry the sporangia that produce the male microspores as well as female megaspores.
Nonflowering plants like ferns, mosses, etc other nonflowering plants have reproductive organs called antheridium and archegonium. The male gametophyte's primary source of sperm cells would be the antheridium (male gametes). Numerous sperm will be produced by the antheridium for fertilization.
Therefore, The organ in many nonflowering plants which produces an egg cell is the strobila or cone produce.

Glucose molecules bond together in a process known as dehydration synthesis. What
happens in this process?
The reaction uses water molecules to break the bonds in each glucose.
O4 water molecules are lost from each bond broken
O 4 Water molecules are used for every
O 1 water molecule is lost (OH + H) for every bond formed
Glucose molecules bond together in a process known as dehydration synthesis, and in this process, 1 water molecule is lost (OH + H) for every bond formed. The last option is correcting the glucose dehydration reaction.
What is glucose dehydration?The macromolecules, such as the polysaccharides and proteins, are formed by the dehydration reaction, and in this reaction, the water is lost to make the polymer. The single glucose molecules unite with each other and release a single unit of water to form the polymers, and in this way the polymers such as glycogen, starch, and cellulose are formed.
In the case of proteins, each amino acid dehydrates and releases one molecule of water, forming the polypeptide chain. As a result of the dehydration process, the monomers combine to form the polymer, which can be structural or functional.
Hence, for every bond formed, one water molecule (OH+H) is lost. The last option is correct regarding the glucose dehydration reaction.

How does an atom become a positive ion?
O A. It loses an electron.
O B. It gains a neutron.
O C. It gains an electron.
D. It loses a neutron.
Answer:
The answer is C
Explanation:
Mark the brainly
Answer:
A. It loses an electron
Explanation:
An atom becomes a positive ion when it loses an electron (then there are more protons than electrons in the atom) when it is trying to reach stability. This is called a Cation. The opposite of this is an Anion, when an atom gains an electron to reach stability and becomes a negative ion (because the number of electrons are higher than the number of protons).

Describe why some water uses are called consumptive
Answer:
Consumptive rates are so high because water that is applied to a field is considered lost to the immediate water system. It either gets evaporated, used by the plants, or leaves the field as run-off. In addition, leaks or evaporation cause loss while water is being transported from the source to the field, often over great distances.

What is the difference between the way energy puts limits on life and the way phosphorus does so?
Adenosine triphosphate (ATP) production, the creation of sugar and alcoholic esters, and other energy-transfer processes all need phosphorus.
What is the role of phosphorus in energy?
In many enzymatic processes, where inorganic phosphorus regulates the rate of reaction, phosphorus also serves a regulatory purpose in addition to these other tasks.
This holds true for everything from exploration to the development of young children and is determined not by our muscles and lungs but rather by the amount of energy we can obtain from food.
It has a significant impact on how the body utilizes fats and carbs. The production of protein by the body is also necessary for the development, upkeep, and healing of cells and tissues.
Therefore, the way energy puts limits on life and the way phosphorus is different.

During the process of fertilization and pregnancy, which becomes implanted on the uterine wall? (1 point)
gamete
O sperm
Oblastocyst
embryo
Answer:
That is C.) blastocyst. I hope this helps! :)
During pregnancy after fertilization, the embryo gets implanted in the uterine wall. So the correct option is D.
What is an embryo?The embryo is the stage of an animal's early development when it is within an egg or a mother's uterus. When referring to an unborn person, the phrase is used up to the end of the seventh week after conception; starting with the eighth week, the term "fetus" is used.
When an ovum and a sperm unite to form a sexually reproducing organism, the outcome is a zygote, or fertilized egg, which goes through a series of divisions known as cleavages as it travels down the fallopian tube. A hollow ball known as a blastula is created by the cells following many cleavages.
In most animals, the blastula adheres to the uterine lining, causing the placenta to develop and begin supplying the developing fetus with nourishment from the mother. The yolk feeds the embryo in lower animals.
The embryo differentiates into three types of tissue through the process of gastrulation: the ectoderm, which produces the skin and nervous system; the mesoderm, from which connective tissues, the circulatory system, muscles, and bones develop; and the endoderm, which produces the digestive system, lungs, and urinary system.
Therefore the correct option is D.

Explanation:
During photosynthesis, plants and other photosynthetic organisms release oxygen into the atmosphere. Without this process, Earth's atmosphere would have little oxygen. Identify two reasons why photosynthesis is critical for animals to produce energy for life functions. How would this effect the animals ability to create the four main types of biomolecules.
Answer:
Without oxygen from photosynthesis animals would not have oxygen for the four type of biomolecules which all require oxygen. Carbon hydrogen and oxygen is carbohydrates and same for lipids. Proteins would not have the oxygen for CHON which is carbon hydrogen oxygen and nitrogen. And nucleic acids which are CHONP carbon hydrogen oxygen nitrogen and phosphorus would not have oxygen. And without oxygen the animals would die and not be able to produce these biomolecules.
Answer: To grow and reproduce, all creatures require energy. Cellular respiration is utilized by many organisms (including all plants) to create ATP, which is needed for cellular energy. As a substrate, carbohydrates such as glucose are used in the respiration reaction. Plants produce their own fuel for respiration through photosynthesis, but humans consume food to do so. Plants would not be able to breathe if photosynthesis did not occur. Furthermore, carbohydrates created during photosynthesis are needed to construct plant cell components such as the cellulose cell wall.

What is the definition of period?
1) cycles per second
2) vibrations per hour
3) seconds per cycle
4) Number of vibrations
Period is defined as cycles per second. Therefore option (A) is correct.
What are the characteristics of period?A period T is the time required for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the period of the wave decreases.
The unit for time period is 'seconds'. Frequency and time period are in a reciprocal relationship that can be expressed mathematically as: T = 1/f or as: f = 1/T. Orbital period is the time for something to go round (orbit) something else.
Frequency and Period are in reciprocal relationships and can be expressed mathematically as: Period equals the Total time divided by the Number of cycles.

que Graphing and Analyzing Data (Cricket Chirps) In order to determine if cricket chirps are influenced by temperature, scientists recorded the chirps at different temperatures over a month-long period. Day Temperature (Fahrenheit) Average Number Chirps (per 15 sec) 5/05 54 15 5/09 60 21 5/11 58 19 5/20 68 29 5/22 64 25 5/27 72 33 6/01 80 44. 6/06 70 31
Answer:
D16.5 degree F. Explanation : when x = 9: y = 25.2 + 3.3(9) = 54.9 deg. when x = 5 more chirps or 14: y = 25.2 + 3.3(14) = 71.4 deg. 71.4 - 54.9 = 16.5 deg.
Explanation:
ok
The first cricket: the sky's the limit. 9 chirps in a quarter of a minute, or 15 seconds, are equivalent to 36 chirps in 60 seconds. In the same amount of time, the first cricket makes 12 chirps.
When x = 9: y = 25.2 + 3.3(9) = 54.9 deg. When x = 5 more chirps or 14: y = 25.2 + 3.3(14) = 71.4 deg. 71.4 – 54.9 = 16.5 deg.
What is the temperature affect the chirping of cricket?As the temperature rises, it gets simpler to reach a particular activation energy, which speeds up chemical processes like the one that causes a cricket to chirp.
On the other hand, as the temperature drops, the reaction speeds slow and the chirping also decreases.
Although the amount of light has no bearing on their chirp, temperature does: warmer air causes a faster chirp.
The number of cricket chirps over a 15-second period multiplied by 37 will often give you the temperature in degrees Fahrenheit.
Therefore, The cricket is chirping because of the vibrations produced while the scraper is moved along the file.
