Which group has the smallest dispersal distances
a) Seaweeds
b) Fish
c) Crabs
d) Marine Snails
Answer:
d) Marine Snails
Explanation:
Marine Snails has the smallest dispersal distance because of their slow mobility and stick to one place. These marine snails have very limited mobility when they are adults and spend their majority of lifetimes in a small geographical area. Dispersal distance refers to the distance a species can move from an existing place or population or the parent organism. According to this definition we can say that marine snails have the smallest dispersal distances.

In trophic webs, any change affecting one of the links affects the superior and the immediately anterior link. Option b) decreased, increased, decreased.
What is a trophic web?
The trophic web is the interaction between different organisms involving transference of energy when some of them feed on the other ones. The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
• The first link corresponds to a producer organism -autotroph-.
• The following links are the consumers -heterotrophs-: herbivores and carnivores.
• The last links are the decomposers that degrade organic matter from dead organisms.
Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.
Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
To answer this question, we need to think about predatio-prey relationship.
In this food chain we know that
Urchins feed on kelp. Sea otters feed on urchins, and orcas feed on sea otters.So, the more orcas there are, the less sea otters there will be, because many orcas are feeding on them. Sea otters' population decreases in size.
↑ ocas ⇒ ↓ sea otters
Since there are fewer sea otters, the urchin population will be able to increase in size, because they are not affected by sea otter predation as they used to be.
↓ sea otter ⇒ ↑ urchins
Finally, the more urchins there are, the more affected kelp will be, because predation on them by urchins increases.
↑ urchins ⇒ ↓ kelp
The correct option is then option b. decreased, increased, decreased
↑ ocas ⇒ ↓ sea otters ⇒ ↑ urchins ⇒ ↓ kelp
decrease increase decrease

True or false , thr vertebrae starts at the base of the skull and continues to the pelvis
Answer:
False
Explanation:The pelvis is a group of fused bones and may be considered the first step in the linkage of the axial skeleton (bones of the head, neck, and vertebrae) to the lower appendages. The part of the axial skeleton directly communicating with the pelvis is the lumbar spinal column. The femur is the appendicular skeletal bone connected to the pelvis at the acetabulum, a bony ring formed by the fusion of three bones: the ilium, ischium, and pubis. The main function of the pelvis is support for locomotion, as it provides attachment points for muscles, tendons, and ligaments. While stiff joints bind the axial skeleton to the pelvis, the appendicular skeleton is joined via a relatively free-floating ball and socket joint between the femur and the acetabulum to allow maximal mobility of the joint.[1]
In discussing the pelvis, a distinction can be made between the "pelvic spine" and the "pelvic girdle." The pelvic girdle, also known as the os coxae, Latin for “bone of the hip,” consists of the fused bones identified individually as the ilium, ischium, and pubis. The ring of this girdle is closed in the anterior by the pubic symphysis between the left and right pubic bones, and in the posterior between the left and right ilia and the sacrum at the sacroiliac joints. The pelvic spine consists of the sacrum and coccyx. Together these two parts form the bony pelvis.

how do you think the study of heredity may help the human race in the future
This helps determine which traits are passed down from parent to child. Successful traits are more frequently inherited and change species over time.
What is heredity?Heredity refers to the specific mechanisms by which characteristics or traits are passed down through generations via genes. Genes contain the instructions for producing specific proteins.
Normally, heredity is defined as the process by which an offspring inherits predisposed characteristics from its parent cell.
It is the process of passing down genetic traits from parents to offspring, which is initiated by recombination and gene segregation during cell division and fertilization.
Understanding genetic factors and genetic disorders is essential for learning more about health promotion and disease prevention.
Some genetic changes have been linked to an increased risk of having a child with a birth defect or developmental disability, as well as developing diseases like cancer or heart disease.
Thus, this way, the study of heredity may help the human race in the future.

Why do some non-'ideal' traits exist in organisms?
Explanation:
They are helpful in mate selection rather than being mostly beneficial to survival
7. Slime molds are fungus like protists, but they are not fungi. Why?
Answer:
Because they can move
Explanation:
Fungi cannot make food themselves so they depend heavily on hosts. Also fungi lack the proper cilia to move, so they use spores instead to "move".
In the case of slime mold, they are like an animal fungus per se. They are like Protozoa in their amoeboid plasmodial stage and similar to true fungi in spore formation.
Charles Darwin referred to this as survival of the fittest. Over time, it results in changes in the inherited characteristics of a population. A. Natural Selection B. Evolution. C. Genetic Variation D. Extinction

Emest Rutherford's atomic model included a nucleus comprised of positive particles called protons. Later, James Chadwick discovered neutrons. How did
Chadwick's discovery change the atomic model?
A The new model showed a negatively charged nucleus.
B. The new model showed a neutrally charged nucleus
C. The new model showed a larger electron cloud.
D. The new model showed a nucleus with two types of particles
Answer:
D
Explanation:
It can't be A as nuclei must be positive.
It can't be B as nuclei must contain at least one proton, and no electrons.
Technically C may be true, but the question is asking about the nucleus. Not the electron cloud. Electrons aren't found in the nucleus. Only protons and neutrons.

What are the generations which has been used in the cross?The first generation crossed which included the true breeding parents are the P generation plant. This produces the two subsequent generations which are the first filial generation (F1) and the second filial generation (F2).
In his breeding experiments, mendel first crossed true-breeding plants to produce a second generation, which were then allowed to self-pollinate to generate the offspring. Gregor Mendel performed series of experiments with pea plant to determine the law that governs inheritance.
In the parental generation (P-generation), He crossed a truebreeding plant that is dominant for a particular trait i.e. a plant that contains the same dominant alleles in its genotype and a truebreeding plant that is recessive for a particular trait i.e. contains same recessive alleles for the same gene.
Therefore, Sand has the smallest particle size and clay has the biggest particle size while silt is in between the two. The correct order will be clay – silt – sand.

the blood proceeding away from the glomerulus is relatively thick.
why
The two types of corpuscles, proteins, and other big molecules that make up the thicker portion of the blood still present in the glomerulus after ultrafiltration are transported by the efferent arteriole. As a result, the blood leaving the glomerulus is rather thick.
What is glomerulus?A small amount of connective tissue holds a collection of capillary blood capillaries together. It is created by renal afferent arterioles. The efferent renal arterioles are responsible for removing blood from the glomerulus.
After being filtered into Bowman's capsule, the efferent arterioles exit the glomerulus and travel down the nephron to remove any reabsorbed material via the vasa recta. Through the renal vein, blood leaves the kidney.
Therefore, corpuscles, proteins, and other big molecules that make up the thicker portion of the blood are still present in the glomerulus after ultrafiltration.

The purpose of mitosis is to create two new perfectly identical cells when either there is a need to replace old or damaged cells and to reproduce asexually by making new cells. Some organisms use mitosis to replace body parts. For example starfish replace lost arms by mitosis. Some organisms such as the hydra use mitosis to produce genetically identical offspring.
There are four stages of mitosis: prophase, metaphase, anaphase and telophase.
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres
2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)
3) Anaphase: sister chromatids are pulled to opposite poles of the cell
4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin
● The order of the stages of mitosis can be remembered using the mnemonic PMAT.
