Why do many water animals not have a well developed blood system?
The simplest animals, such as the sponges (Porifera) and rotifers (Rotifera), do not need a circulatory system because diffusion allows adequate exchange of water, nutrients, and waste, as well as dissolved gases. Instead, gases, nutrients, and wastes are exchanged by diffusion.

What is the microscopic nature of a cell ?
Why nucleus is said to be the controller of cellular activities ?
How is a cell adapted to its small size?
Answer:
No 1 answer They require sophiscated tools. The microscopes help in the study of cells. The molecular study of the cells are performed by the help of electron microscope. So, we can say that cells are microscopic in nature.
Explanation:
No 2 answer The nucleus is the largest and most prominent of a cell's organelles (Figure 3.7). The nucleus is generally considered the control center of the cell because it stores all of the genetic instructions for manufacturing proteins.
No 3 answer Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.

How long does it take the moon to rotate on its axis?
about 25.3 days
about 27.3 days
about 30 days
about 2 months
Answer:
27.3 days
Explanation:
The Moon takes 27.3 days to rotate on its axis as the Moon takes 29.5 days to revolve around the Earth. So, the correct option is B.
What is Rotation?Rotation is defined as the circular movement of an object around a central axis where a two-dimensional rotating object has only one possible central axis and can rotate in a clockwise or counterclockwise direction, while a three-dimensional object has an infinite number of possible centers that is axes and rotational directions.
The Moon orbits the Earth in the same direction, completing one orbit relative to the vernal equinox and the stars in about 27.32 days while one orbit relative to the Sun takes about 29.53 days.
Thus, the Moon takes 27.3 days to rotate on its axis. So, the correct option is B.

Which of the following shows the stage of mitosis in the correct order?
Prophase, prometaphase, metaphase, anaphase, telophase, cytokinesis is the correct order of mitosis. Therefore, option (B) is correct.
Mitosis is a cellular process that ensures the accurate division of a cell's genetic material into two identical daughter cells. It consists of several distinct phases that occur in a specific order.
Interphase: The cell prepares for division by growing, duplicating its DNA, and synthesizing necessary proteins.
Prophase: Chromatin condenses into visible chromosomes, the nuclear membrane disintegrates, and spindle fibers form.
Metaphase: Chromosomes align at the center of the cell, known as the metaphase plate, and attach to spindle fibers at their centromeres.
Anaphase: Sister chromatids separate and are pulled to opposite ends of the cell by the spindle fibers.
Telophase: Chromosomes reach the opposite poles of the cell, and new nuclear membranes form around them. The chromosomes begin to decondense.
Cytokinesis: The cytoplasm divides, leading to the formation of two distinct daughter cells, each containing a complete set of chromosomes.

3) In order for an ecosystem to thrive, it needs to exist in a form of harmony and balance between its biotic and abiotic factors. Describe how small changes to both biotic and abiotic components can have major effects on an ecosystem.
Answer:
Changing temperature causes extinction or removal of organism from that place.
Explanation:
Small changes to both biotic and abiotic components can have major effects on an ecosystem because these are the factors on which the ecosystem depends. For example, if the temperature of the ecosystem increases from its limit, it makes the environment unfavourable for the organism so due to this change, the organism migrated to other location otherwise they will die due to unfavourable environment.

if the mass extinction event that had wiped out the dinosaurs had not occurred, could dinosaurs rather than mammals have evolved into an intelligent organism resembling modern day humans ?
Answer:
If the mass extinction even that had wiped out the dinosaurs had not occurred, dinosaurs would've evolved. Though maybe not into organisms that resemble modern-day humans, they would've become better versions of themself. However, some of them might've died out naturally due to climate change and other natural disasters.
If the mass extinction event had wiped out the dinosaurs and not occurred. The dinosaurs would not have been converted into an intelligent organism like humans, because evolution may be bad or good, nothing is always evolution that results in good traits.
What are dinosaurs?Dinosaurs are extinct reptiles, that were very big, and they were both herbivorous and carnivorous. These animals were present 56 million years ago. They got extinct because of an unknown reason, but scientists say that they got extinct due to the falling of meteorites.
If dinosaurs had not been extinct, they would be evolved according to the changes in the environment. They would not be converted into human intelligence.
Therefore, since evolution can be either positive or negative, there is no guarantee that it will always produce positive features in organisms, the dinosaurs would not have evolved into sophisticated beings like humans.

The arrows in a food chain show: a Who eats who b Heat energy being lost c The movement of energy between organisms d The route of food to the shops
Answer:
c The movement of energy between organisms
Explanation:
Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.
The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).
This ultimately implies that, the arrows in a food chain show the movement of energy between organisms such as from producers which are autotrophs or self-feeders such as plants to the tertiary consumers.
Furthermore, a list of the types of organisms in an eco pyramid are;
I. Producers: these are autotrophs or self-feeders such as plants.
II. Primary consumers: these are herbivores that typically feed on plants such as a goat or deer.
III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.
IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.
Answer: The arrows in a food chain show (The movement of energy between organisms). The correct option is C.
Explanation:
In an ecosystem, a food chain shows the transfer of energy and nutrients ( food) from organisms to organisms in a feeding pathway. Instead of giving functional group names such as primary producer, primary consumer and so on, in a good chain, the organism at each step is identified. Thus,
Grass-------> Zebra ---------> lion
(Primary (Primary ( secondary
producer). consumer) consumer)
this is an example of a simple food chain in a grassland ecosystem. This ARROWS represented above shows the direction of energy flow through an ecosystem.
Furthermore, the grass traps solar energy and stores it as chemical energy in the food made during photosynthesis. When eaten by Zebra, which is the primary consumer, the energy stored in the grass is transferred to the consumer. This transfer is inefficient as some of the stored chemical energy is lost as heat. When the zebra is eaten by a Lion,which is the secondary consumer.

what scientific term is used to describe all the genes of one organism?
Answer:
The scientific term used to describe all of the genes in an organsim is the genome.
Genome term is used to describe all the genes of one organism, it forms the genotype of an organism.
What is a genome?the entirety of an organism's genetic makeup, or DNA. Nearly every cell in a person's body has a complete copy of its genome. Everything a person needs to grow and develop is encoded in their genome.
Each and every one of the body's cells, such as the skin cell or the liver cell, carries the following set of instructions: DNA makes up the instructions in our genome.
The genome's main job is to preserve, express, and store the genetic material that gives rise to a cell's structural and functional machinery. The genome is a significant part of the cell's structural makeup, nevertheless. Hence, the Genome term is used to describe all the genes of one organism.
