Answer:
From other seeds
Explanation:
They grow more seeds form the one seed
Answer:
From plant reproduction.
Explanation:
Plants produce flowers to make seeds. To make a seed a flower must be pollinated. Pollen from the male part of one flower travels to the female part of another flower where the seeds are made. Most, but not all plants, have both male and female parts inside one flower. The stigma is usually in the centre and the stamens, which produce the pollen, cluster around it. The petals act like an advertisement to attract various animals, which will carry the pollen from one flower to another.

What happens to the membrane protein (gray) when it is activated by the signal molecules?
Answer:
The receptor protein that is embedded in the cellular membrane must accept the signal.
Explanation:
When it receives the signal this protein will then go through a conformational change. This will change the shape and how it interacts with the molecules around it. Different receptor protein will act in different ways.
Answer:
As their name implies, GPCRs interact with G proteins in the plasma membrane. When an external signaling molecule binds to a GPCR, it causes a conformational change in the GPCR. This change then triggers the interaction between the GPCR and a nearby G protein.
What happens to the membrane protein (gray) when it is activated by the signal molecules?
The membrane protein interacts with the nearby GPCR.

A student creates an experiment to determine the effects of oxygen on the growth of a water plant. The student fills three containers with water and adds an aquatic plant to each. Container 1 is open to the air, container 2 has a lid that prevents the exchange of air, and container 3 has a lid with a tube that pumps air into the container. After three weeks, the student observes that containers 1 and 3 have healthy green plants, while the plant in container 2 has not grown, and the leaves show browning areas.
Which explanation provides the reason for the difference in the growth of the plant in container 2?
Answer:c

Answer:
Explanation:
An archegonium (pl: archegonia), from the ancient Greek ἀρχή ("beginning") and γόνος ("offspring"), is a multicellular structure or organ of the gametophyte phase of certain plants, producing and containing the ovum or female gamete. The corresponding male organ is called the antheridium.

How does your body respond to a decrease in blood glucose
You are maintaining a small population of fruit flies in the laboratory by transferring the flies to a new culture bottle after each generation. After several generations, you notice that the viability of the flies has decreased greatly. Recognizing that small population size is likely to be linked to decreased viability, the best way to reverse this trend is to cross your flies with flies from another lab.

what is observable evidence that earth is surrounded by a magnetic field?
Answer:
Evidence for these geomagnetic reversals can be found in basalts, sediment cores taken from the ocean floors, and seafloor magnetic anomalies. Reversals occur nearly randomly in time, with intervals between reversals ranging from less than 0.1 million years to as much as 50 million years.
Please explain the health principles that are practiced by Rastafarians in Trinidad and Tobago and how this information prepares you as a nurse to better serve this community.
Answer:
Rastas, as members of the movement are called, see their past, present, and future in a distinct way. Drawing from Old Testament stories, especially that of Exodus, they “overstand” (rather than understand) people of African descent in the Americas and around the world to be “exiles in Babylon.” They believe that they are being tested by Jah (God) through slavery and the existence of economic injustice and racial “downpression” (rather than oppression). Looking to the New Testament book of Revelation, Rastas await their deliverance from captivity and their return to Zion, the symbolic name for Africa drawn from the biblical tradition. Ethiopia, the site of a dynastic power, is the ultimate home of all Africans and the seat of Jah, and repatriation is one goal of the movement. Many (though not all) Rastas believe that the Ethiopian emperor, His Imperial Majesty Haile Selassie I, crowned in 1930, is the Second Coming of Christ who returned to redeem all Black people. The movement takes its name from the emperor’s precoronation name, Ras Tafari.

In mitosis the daughter cells are identical to the parent cell. How do the cells produced during meiosis differ from those produced from mitosis
Answer:
The cells produced during mitosis are identical but cells produced in meiosis are different.
Explanation:
This is because in mitosis, there is no crossing over, but crossing over occur in meiosis. During crossing over, there is swapping of the genetic material.
a circle fence sourrounding a small yard mesure 84 meters in length if you walk from one side from the other through the middle what is the distance across the small yard
Answer: 26.75 meters.
2πr = 84
2 * 3.14 * radius = 84
radius = 84/6.28
r= 13.375
So the diameter will be 13.375 + 13.375 which is 26.75 meters.
why is the kidney bean shaped
Answer:
Because the shape helps to keep the composition of blood in the body balanced to maintain good health.
Explanation:
The kidneys are two 'bean-shaped' organs in the lower back that serve to conserve water, maintain blood osmolarity, help in acid-base balance, and filter blood plasma. Urine is the fluid product produced by the kidneys which is excreted as waste from the body.
Answer:
The bean-shaped kidneys filter waste products out of the bloodstream and dispose of them by creating urine. Urine is made of these waste products dissolved in wate

How do organisms depend on and compete for biotic and abiotic factors?
Your answer should include at least 6 sentences to explain the claim, evidence and reasoning.
Answer:
Organisms depend on and compete for both biotic and abiotic factors in an ecosystem. A few abiotic factors are sunlight, water, and territory. Plants compete for sunlight and water, and they depend on those factors for their survival. Biotic factors would include plants, bacteria, and other animals. Consumers of these biotic factors compete for them because they depend on them for their survival.

it can be said that all cells life begin and end with this process ?
Replication
Meiosis
Mitosis
Cytokinesis
all cells life begin and end with this process by the process of meiosis
What is meiosis ?
Meiosis is the process where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.
Humans have 46 chromosomes in every cell, where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.
Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.
Secondly Prometaphase I where Spindle fibres attach to the centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.
Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.

What does an alcoholic beverage contain that is a central nervous system depressant? 
Answer:
interferes with release of neural transmitter GABA
Explanation:
Alcohol is a central nervous system depressant, meaning it slows down brain functioning and neural activity. Alcohol does this by enhancing the effects of the neural transmitter GABA
depressants essentially "look" like the neural transmitter and so they go in and block the plasce in the brain between synapses, so when the body tries to release GABA, it appears as if it is already filled in, but in reality it is the alcohol that has filled it. once they start buidling up, they block enough that it impairs brain activity
Answer:
GABA
Explanation:
gamma-aminobutyric acid (GABA)
which of the following are photosynthetic organisms?
Answer:
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 1). Because they use light to manufacture their own food, they are called photoautotrophs (literally, “self-feeders using light”).
How does your body respond to an increase in the need for energy----why would you need more energy?
Answer:
Exercise can boost energy levels by raising energy-promoting neurotransmitters in the brain, such as dopamine, norepinephrine, and serotonin, which is why you feel so good after a workout. Exercise also makes muscles stronger and more efficient, so they need less energy, and therefore conserve ATP.
