is gene paired on endosperm cell?
Answer:
yes
Explanation:
What is the genetic makeup of endosperm?
One sperm fuses with the egg to form a diploid zygote, and the other sperm fuses with two female-gametophyte nuclei (known as polar nuclei) to form the triploid primary-endosperm nucleus. Therefore, the endosperm, which devel- ops from this triploid nucleus, has an unusual genetic composition

in plants the fertilized egg develops into a multicellular _________ within a female gametangium.
Answer:
Once fertilization has occurred, the embryo develops within the female gametophyte, and the ovule becomes the seed, complete with a food source (the gametophyte tissue) and a seed coat (the integument).

In your own words, what is a trophic cascade?
Answer:
A trophic cascade is a side-effect when a trophic level (species) of the ecosystem is reduced or removed. Their ecological species interactions keep entire ecosystems balanced. Hence, suppressing their numbers or changing their behavior due to predation risk, results in an ecological imbalance or a trophic cascade.
Explanation:
BRAINLIEST PLEASE ;)Answer:
Tropic cascades in an eco-system is when a prey changes its behavior due to the predators attacks, thereby increasing in numbers indirectly for the survival of the predators.

Summarize the lytic cycle. (1 point)
The viral DNA incorporates itself with the host cells and replicates whenever the host cell replicates itself.
A virus copies its genetic material and then splits its cell membranes in half to form identical viruses.
A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.
A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.
Answer: A virus injects its genetic material into the host cell, copies itself using the host's structures and resources, and then forms new viruses that burst out of the host cell
The lytic cycle is one of the two main life cycles of viruses, the other being the lysogenic cycle. In the lytic cycle, a virus infects a host cell and hijacks its cellular machinery to replicate and produce new virus particles, or virions.
The correct option is D .
The lytic cycle is rapid and results in the destruction of the host cell. It is often associated with acute infections, where the symptoms of the infection are more severe and appear relatively quickly. Examples of viruses that follow the lytic cycle include the flu virus (influenza), the common cold virus (rhinovirus), and many bacteriophages that infect bacterial cells.
The lysogenic cycle, on the other hand, is characterized by the integration of the viral genetic material into the host cell's genome, allowing the virus to remain dormant for a period before switching to the lytic cycle.
Hence , D is the correct option

Yifei and Santos are making a diorama on the ecological role of organisms. Yifei wants to show the omnivores eating both plants and other animals, and the herbivores eating other animals. Santos wants to show the omnivores eating only other animals, and the herbivores eating both plants and animals. Who is right?
Answer:
None of them are correct because omnivores, from the root word "Omni" meaning "all", means omnivores eat both plants and animals. Then, herbivores only eat herbs, meaning plants, so both of them are wrong. Animals that eat other animals but not plants are called carnivores.

are water hyacinths still a problem till this day in the us?
water hyacinths still a problem till this day in the us
the answer is yes !!!!
water hyacinths also known as Pontederia crassipes considers as most the worst aquatic weed in the world.
They are the fastest growing weed that allowed the plant to build huge populations in its ranges of introduction. They develop dense mats on the surface of the water and becoming a major weed problem.
due to their dense layering in the surface the sun light cant travel properly in the water and the consumption of oxygen is also taken up by them hence it result the lack of oxygen in the water.
in BENGAL it is also known as the "terror of Bengal"
Explain how ADH is involved in the regulation of water in the body
Answer:
Antidiuretic hormone binds to receptors on cells in the collecting ducts of the kidney promotes reabsorption of water back into circulation, These channels transport solute-free water through tubular cells and back into blood, leading to a decrease in plasma osmolarity and an increase osmolarity of urine.

A plant dies if it’s pholem tissue removed why
A plant dies if it’s pholem tissue is removed. Why?
Answer:-When the phloem is removed, no substance is transported, the plant does not have the necessary requirements to carry out the process (photosynthesis), and finally the plant dies.
Phloem is composed of various special cells called companion cells, phloem fibers, and phloem parenchyma cells.brainliest goes to best answer! Explain the flow of energy as it is transformed through photosynthesis AND aerobic cellular respiration.
Be sure to explain how energy is processed and changed as it passes through and between each process.
EX: Stored energy in gas is converted to heat when you light the stove. This heat is transferred to the food as heat energy while it cooks.
The correct order of flow of energy and its conversion is
Light energyChemical energyPotential and Kinetic energyDuring photosynthesis, plants converts light energy from the Sun into
chemical energy in the form of glucose. Cellular respiration involves the
conversion of chemical energy from glucose into potential and kinetic
energy by body cells
The chemical energy from glucose is converted into ATP which is another
form of chemical energy.The ATP formed helps cells perform various
activities and state of rest such as sleeping in the body through the
conversion of the chemical energy into kinetic and potential energy
respectively.

A rat has 42 chromosomes in eath somatic call. How many chromosomes are in each gamete
Answer:
21 chromosomes
Explanation:
Somatic cells are a diploid which have 2 sets of chromosomes. If two sets are 42 chromosomes, one set must be 21 chromosomes. Gametes are a haploid which have only 1 set of chromosomes. So in each gamete, there should be 21 chromosomes.

The properties of water are the result of multiple factors including; polarity and hydrogen bonding. Which property of water is not a result of polarity?
A.Water dissolves salts and sugars.
B.Water will become less dense when frozen.
C.Water is transparent and lets sunlight pass through.
D.Water will from a spherical bead due to surface tension
Water is transparent and lets sunlight pass through. Therefore, the correct option is C.
Water's transparency and ability to pass through sunlight is not just a product of its polarity. This is mainly because water absorbs only specific wavelengths of light, particularly those in the visible spectrum, while allowing other wavelengths to pass through. Rather than being a direct result of polarity, this property is related to the electrical structure of water molecules and their interactions with light. On the other hand, the interplay of water polarity and hydrogen bonding is the reason for the A, B and D properties, respectively.
Therefore, the correct option is C.
