b) They contain nutritive tissue for the embryo
c) They are also referred to as spores
d) They consist entirely of diploid cells.
Answers
The following statements regarding the seeds are true:
a) They contain an embryo
b) They contain nutritive tissue for the embryo
d) They consist entirely of diploid cells.
Embryo- The embryo would be the fertilized ovule, a young plant that, under ideal conditions, would develop into a new plant. The embryo of a monocotyledon contains a single cotyledon or seed leaf; that of a nearly all dicotyledon possesses two, and that of a gymnosperm contains two or even more.
Tissue- A tissue would be a cluster of cells with comparable structures as well as roles. A nonliving material called the intercellular matrix fills the space between both cells. Some tissues may have a lot of this, while others may not.
Therefore, the correct answer will be option(a), option (b) and option(d).

The process whereby Fern plants reproduce asexually using two by growing an offspring from its roots or by releasing reproductive
cells into the air that will later grow into new plants are vegetative reproduction and spores; option A.
What is asexual reproduction?Asexual reproduction is a form of reproduction in which only one parent is involved in the production of offspring.
Asexual reproduction does not require the fusion of the male and female gametes to form an embryo which then develops into a mature offspring.
Hence, asexual reproduction is the most dominant form of reproduction in living organisms as it requires less energy or time for the production of offspring.
Some forms of asexual reproduction are:
vegetative reproduction - the offspring is produced from a part of the parent as an offshootSpore formation - reproductive cells are produced which are then dispersed and grow during favorable times.Learn more about asexual reproduction at: https://brainly.com/question/12176249

Which of these describes the similar functions of capsids and nuclear membranes?
Answers
The similar functions of capsids and nuclear membranes Both protect genetic information for the structures.
The main similarity and function of capsid membranes and nuclear membranes is to provide protection. Most viruses use the canonical nuclear pore complex NPC to import their genome into the nucleus. The viral capsid which is larger than the nuclear pore is degraded before or during passage through the NPC allowing entry into the core of the genome.
Virus structure. In simpler viruses, the virion consists of a single nucleic acid molecule surrounded by a protein shell the capsid. Together the capsid and its encapsulated nucleic acid form a nucleocapsid.

Why it is incorrect to say that humans evolved from chimpazees? What would be a more accurate description?
Answers
To say that humans evolved from chimpanzees is a common misconception of evolution caused by the confusion between Lamarckism and Darwinism.
Lamarck stated that evolution followed the chain of being and eventually the organisms would evolve into more "complex" beings. We know now that evolution doesn't work that way.
It would be more accurate to say that humans and chimpanzees come from a common ancestor because the species we can actually find are not transforming into others that also exist. If we map the species, they would be at the points of tree branches and the common ancestor between them would be in the nodes.
Many animals travel in groups, while some live and travel alone. Scientists are interested in whether traveling in groups or individually makes a difference in the time it takes animals torecognize and escape a predator. Scientists observed three different populations of animals and recorded the response time to predators for animals traveling individually and in groups.The average response time to predators for these different animals are presented below.Which conclusion is best supported by the data shown in the graph?A.Animals traveling in groups respond faster to predators, allowing them to outcompete others for food more successfully.B.Animals traveling individually respond faster to predators, allowing them to outcompete others for food more successfully.C.Animals traveling in groups respond faster to predators, allowing them to escape more successfully.D.Animals traveling individually respond faster to predators, allowing them to escape more successfully.
Answers
Consider the following diagram:
Defense mechanisms against predation are evolutionary adaptations that serve animals, potential prey, in their fight against predators. One of the defense mechanisms is to travel in groups. For example, sometimes fish travel together to avoid predators such as sharks, killer whales, or dolphins. In fact, the graph shows that groups respond faster to predators.
According to this information and the given diagram of the problem, we can conclude that the correct answer is:

Answers
The intron acting in this scenario is A carbohydrate. Option A.
The most important function of introns is to allow alternative splicing, allowing multiple proteins to be made from a single gene. Some introns are spliced and further processed to encode functional RNA molecules. The first stage is the genomic intron, which is the DNA sequence of the introns.
Introns are regions within a gene that do not remain in the final mature mRNA molecule after transcription of the gene and do not code for the amino acids that make up the protein encoded by that gene. Most protein-coding genes in the human genome consist of exons and introns. Introns are nucleotide sequences in DNA and RNA that do not directly code for proteins and are removed during mRNA maturation by RNA splicing during the precursor messenger RNA stage.

Answers
Antibodies are made up of protein macromolecules composing of 4 glycoproteins. Proteins are moved in vesicles from the endoplasmic reticulum to the Golgi apparatus, where they undergo additional processing and sorting before being sent to lysosomes, the plasma membrane, or secretion from the cell.
Protein sorting and targeting to the correct locations are significant undertakings because of the intricate internal structure of eukaryotic cells. While translation is still active, the first stage of protein sorting takes place. On ribosomes that are attached to the endoplasmic reticulum membrane, numerous proteins that are destined for the endoplasmic reticulum, the Golgi apparatus, lysosomes, the plasma membrane, and secretion from the cell are created. The endoplasmic reticulum, where protein folding and processing occur, receives the polypeptide chains as translation continues.
So, the antibodies have to go through endoplasmic reticulum, Golgi apparatus , lysosomes and then through plasma membrane before being released from the cell.

what is unique about transduction compared to normal bacteriophage infection?
Answers
The distinctive feature is that DNA gets transferred from one cell's chromosome to another by the process of transduction.
Transduction is the term used to describe the process by which a virus spreads its genetic material from one bacterium to another. Bacteriophages are viruses that infect bacterial cells and use them as hosts for the production of more viruses. Transduction is the method through which a virus or viral vector inserts foreign DNA into a cell. The viral transmission of DNA from one bacteria to another is an effective example of horizontal gene transfer. Bacteriophages are a specific class of virus that attack bacteria. The name "bacteriophage" literally translates to "bacteria eater" since it destroys host cells. Thus, transduction is the process by which DNA is transferred from one cell's chromosome to another.

Answers
A plant undergoes high rates of photosynthesis under red light (620-750nm wavelengths) and blue light (450-495nm wavelength). However, under green light (550 nm wavelength) rates of growth are very low. This is because they are themselves green due to the presence of the pigment Chlorophyll.
Green light is reflected back as compared to other colors. this is due to the presence of the green pigment chlorophyll. Since most of the light is reflected back, green light isn't proper for the growth of plants.
In which color range, Photosynthesis takes place at the maximum amount?
The wavelength range of photosynthetically active light is 400–700 nm (PAR). Chlorophyll absorbs light most efficiently in the red and blue portions of the spectrum. So the red and blue light of the visible spectrum has the highest rate of photosynthesis.
Therefore, the rate of growth is lowest in green light.

How does the food move in my body ?
Answers
Answer:
Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ.mark me brainlist if it is helpful to you
When you eat, food enters your alimentary canal. The alimentary canal is a series of organs that form a pathway from your mouth to your anus.
As food moves down this pathway, it's processed and changed to waste. After food is modified to waste, it's pushed out of your body in a bowel movement.
The stomach breaks down food into a liquid mixture. The small intestine absorbs nutrients from the liquid mixture. What remains is a liquid waste. The large intestine (colon) absorbs water from the liquid waste, converting it into solid waste (stool).
Nerves throughout your alimentary canal tell your muscles how fast to contract. Muscles within the intestines contract to move food and waste through the digestive tract. The rectum stores stool until a movement occurs. The anus is the opening where stool leaves the body.

What is food web?
A hawk consumes a snake after it has consumed a frog, a frog after it has consumed a grasshopper, and so on.A food web demonstrates the numerous ways in which plants and animals are interconnected.Different species of organisms can interact in a variety of ways.They can be rivals or symbionts—long-term allies with a strong relationship.Or, of course, they may do what we frequently see in nature documentaries: one of them could chomp down on the other!In other words, they could be a link in a food chain.A food chain in ecology is a group of creatures that consume one another to transfer nutrients and energy from one to the next.If you ate a hamburger for lunch, for instance, you might be associated with the food chain grass right arrow cow right arrow human. But what if your hamburger also had lettuce on it?In that instance, you are also a link in the lettuce-to-human-right-arrow food chain.We can't always properly represent what an organism—such as a human—eats with one straight pathway, as this example demonstrates.A food web that consists of numerous intersecting food chains and reflects the various items an organism can eat and be eaten by may be useful in scenarios like the one described above .We may now examine the flow of energy and nutrients within an ecological community.Let's start by looking at a food chain and a few who-eats-who interactions.A food chain is a group of organisms that are consumed in a linear order, passing nutrients and energy along the way.Let's examine the components of a typical food chain, working our way up from the producers at the bottom.The main producers are found at the bottom of the food chain.Autotrophs, or primary producers, are often photosynthetic organisms like plants, algae, or cyanobacteria.Primary consumers are the organisms that devour primary producers.The majority of consumers are typically plant-eating herbivores, though they can also be algae or bacterium eaters.Secondary consumers are the creatures that consume the primary consumers.Secondary consumers are typically carnivores who devour meat. Tertiary consumers are the organisms that consume secondary consumers.These are carnivores that consume other carnivores, like large fish or eagles.There are additional layers in some food chains, such as quaternary consumers, which are carnivores that eat tertiary consumers.Apex consumers are the organisms at the very top of a food chain.The graphic below shows instances of various levels.Mollusks, who are the principal consumers, devour the green algae, which are the primary producers.The slimy sculpin fish, a secondary consumer, then eats the mollusks for lunch. The sculpin fish is subsequently devoured by a larger fish, the Chinook salmon, a third consumer.Decomposers are occasionally regarded as a separate trophic level.Collectively, they consume decomposing plant materials, a squirrel's half-eaten corpse, or the remains of an eagle that has died. They also consume waste products from organisms at many lower trophic levels.The decomposer level resembles the traditional hierarchy of primary, secondary, and tertiary consumers in certain ways.To learn more about food web refer
