Answer: 5. Amoebocytes have a variety of functions: delivering nutrients from choanocytes to other cells within the sponge, giving rise to eggs for sexual reproduction (which remain in the mesohyl), delivering phagocytized sperm from choanocytes to eggs, and differentiating into more-specific cell types. 6. Sponges form symbiotic relationships with a variety of microorganisms, including bacteria and algae. A symbiotic relationship between organisms is a close ecological association between two species that may be mutually beneficial or may benefit one partner at the expense of the other. However, humans are still damaging sponge populations with weighted nets and even taut fishing lines, which can slice sponges apart by accident. As a rule, anything that can affect the ocean floor will have a negative impact on sponges, as they have never developed protection against impacts. brainliest??

Please I beg you help me. Compare solids,liquids, and gases on the molecular level
Answers
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
Answer:
The compression of solids is difficult, liquids are nearly incompressible but gases can be easily compressed.
Explanation:
molecular arrangements of solids is regular and close, but liquids have irregular and sparse molecular arrangement. Gases too also have more random and sparse arrangements of molecules.
Genetic Technology: Write a scientific explanation to explain the multiple technologies that humans
can use to affect traits in organisms. Use evidence to describe the processes and give examples. Give
at least two examples
Answers
Answer:
Examples of genetic technologies:
- High-yield maize varieties by conventional breeding
- Production of hormones by transgenic or genetically engineered microbes
Explanation:
Genetic improvement refers to the use of technologies in order to develop and select individuals with desired phenotypic traits. These genetic technologies can be divided into 1-conventional genetic improvement approaches based on the development of individuals (e.g., new plant varieties) by crossing together individuals with desired characteristics and subsequent rounds of artificial selection, and 2-modern genetic technologies where genes are directly manipulated in the laboratory through genetic engineering technologies such as, for example, the use of transgenic methods (e.g., DNA microinjection, retrovirus-mediated gene transfer, etc), or the CRISPR-Cas9 genome editing system (which can be used to edit target genes of interest), etc.
Which of the following is a definition of the process of natural selection?
a) In each generation, some individuals may, just by chance, have more offspring than other individuals and their traits will become more common in that population.
b) More advantageous traits in a particular environment allow individuals with those traits to have more offspring; as a result their heritable traits become more common in succeeding generations of the population.
c) Mutations occur at random in a population causing populations to change over time as those mutations are inherited from one generation to the next.
Answers
Answer:
C
Explanation:
Mutations occur oftenly in organisms because it is seen as natural. Not all generations will give offsprings with perfect traits, They tend to have either 50/50 inherited traits from each parent of 100% off a parent if it was asexual reproduction.

Prophase-I occurs over a long duration and involves several complicated changes in meiotic cell division. It is important because genetic recombineiion and variation in sexually reproducing organism occurs due to the events of this phase.
EXPLANATION:❈ Leptotene —
➥ The chromatin network opens out and threads become clear.
➥ The chromosomes are thin, slender and long.
➥ Chromosome number is diploid.
❈ Zygotene —
➥ Corresponding chromosomes become intimately associated.
➥ The process of pairing is known as synapse. It is so exact that pairing is not merely between corresponding chromosomes but between corresponding individual units.
➥ The chromosomes become shorter and thicker.
❈ Pachytene or Pachynema —
➥ The synaptic chromosomes become very intimately associated.
➥ The pair of chromosomes becomes short and thick.
➥ Crossing over occurs at this stage. Chiasmata are clearly seen.
❈ Diplotene —
➥ Homologous chromosomes start separating from one another.
➥ Chiasmata tend to slip out of the chromosomes. This is known as terminalisation of chiasmata.
➥ Chromosomes start separating out but the separation is not complete.
➥ Nuclear membrane and nucleolus start disappearing.
❈ Diakinesis —
➥ The bivalents condense further and get randomly distributed.
➥ The separation of paired chromosomes is almost complete.
➥ Terminalisation of chiasmata is almost complete.
➥ Nuclear membrane and nucleolus disappear.
What is the independent variable of great white sharks travelling distance?
Answers
Answer:
Each year, great white sharks migrate over long distances from their feeding grounds off the central California coast to other feeding grounds far away in the Pacific Ocean. ... That's one reason they migrate from one feeding ground to another, to take advantage of the seasonal bounty.
It's though that a shark can travel up to 50 miles in one day. While we cannot know this for certain as sharks have never been tracked this way, 50 miles is a good estimate

How does bursting of animal cells take place
Answers
Answer:
Swelling and bursting of cells is also known as lysing. This happens when the concentration of solutes inside the cell is greater than the concentration of solutes outside the cell. It has to do with diffusion and osmosis. A high solute concentration relates to a lower water concentration. Since molecules like to diffuse from areas of high concentration to areas of low concentration, water will rush into the cell where the water concentration is lower causing it to swell and lyse.

Explanation:
The difference between pinocytosis and receptor-mediated endocytosis is that _____. Question 14 options: pinocytosis can concentrate substances from the extracellular fluid, but receptor-mediated endocytosis cannot. pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis offers more selectivity. pinocytosis brings only water molecules into the cell, but receptor-mediated endocytosis brings in other molecules as well. pinocytosis increases the surface area of the plasma membrane, whereas receptor-mediated endocytosis decreases the plasma membrane surface area.
Answers
Answer:
The difference between pinocytosis and receptor-mediated endocytosis is that pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis offers more selectivity.
Explanation:
Pinocytosis and receptor-mediated endocytosis are two types of endocytosis.
The first one consists of plasmatic membrane invaginations that capture extracellular fluid with different nutrients and sends it to the inside of the cell in vesicles. The second one, receptor-mediated endocytosis, consists of receptors on the outside of the plasmatic membrane and clathrin proteins on the interior side of the membrane. When the receptors are in contact with its specific molecule, a vesicle surrounded by clathrin proteins, is formed transporting specific molecules to the cell's interior.
