What is the purpose of dermal or friction ridges? What does the imprint of a fingerprint consist of?
Answer: All fingers, toes, feet, and palms are covered in small ridges. These are raised portions of the skin, arranged in connected units called dermal, or friction, ridges. They help us with our grip on objects that we touch. When these ridges press against things, they leave a mark, an impression called a fingerprint.
Explanation:
Answer:
Their purpose on the body is to increase the surface area and increase friction so hands can firmly grasp things, and feet do not slip when walking.
The imprint of a fingerprint consists of natural secretions of the sweat glands that are present in the friction ridge of the skin

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.

events that damage the cell’s regulatory apparatus can cause the uncontrolled division of cells called
Answer:
??????????????
Explanation:
In cancer, uncontrollable cell division occurs because when cells within an organism begin to divide and damage the cell’s regulatory apparatus there is no way to stop this process.
What is cancer?Every cell in the body has a certain lifespan, and at some point during that lifespan, the cell receives instructions to stop dividing and replicating.
But when a cell gets cancer, this regulatory system fails, and the cell enters a phase of uncontrolled cell division. Diseases like cancer can develop when the cell cycle's regular control is disrupted.
When the cell cycle is unchecked, cells can divide randomly and amass genetic flaws that can result in a malignant tumor.
Therefore, damage to the cell’s regulatory apparatus can cause the uncontrolled division of cells called cancer.

remove dirts using hard cloth
Answer:
It can easily remove dirt.
Explanation:
When dirt is present on the hard surface such as car or machines so it can be cleaned by using hard cloth because the dirt attached tightly to the surface which can only be removed from that surface with the help of using hard cloth. Hard cloth has rough surface which easily remove the dirt from the surface as compared to the light cloth so that's why hard cloth is used to remove dirt from the surface.
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.

Explanation:
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.

Can someone write the first paragraph
Hii!!
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.

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.

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.
