Answer:
The correct answer is - option C. endocytosis.
Explanation:
Endocytosis is the transfer process of large molecules from the outside of the cells by internalizing them or engulfing them in vesicles, it is possible by invagination of the surface of the cell to form vesicles.
In an infant, the antibodies like large molecules from the mother to the baby are transferred through the Mother's milk which is entered in the baby's digestive tract via Endocytosis
15. Briefly explain how the gel (or DNA fingerprint) is made after DNA has been amplified.
Answer:
Like the fingerprints that came into use by detectives and police labs during the 1930s, each person has a unique DNA fingerprint. Unlike a conventional fingerprint that occurs only on the fingertips and can be altered by surgery, a DNA fingerprint is the same for every cell, tissue, and organ of a person. It cannot be altered by any known treatment. Consequently, DNA fingerprinting is rapidly becoming the primary method for identifying and distinguishing among individual human beings. DNA fingerprints are also useful in several applications of human health care research and for diagnosis of inherited disorders. DNA fingerprinting is often used in the justice system to link suspects to biological evidence and solve paternity cases.
Explanation:
DNA sample: A DNA sample that will be examined must first be gathered. DNA extraction: Using the lysis process, DNA is then extracted from the sample.
What is DNA fingerprint?Restrictions endonucleases:The DNA fragment is cut at a particular place by a specific restriction enzyme.
Alec Jeffrey, a British biologist, created the DNA fingerprinting technique in 1984 after noticing that some highly variable DNA sequences, or minisatellites, that are repeated inside genes but do not affect their activities.
In DNA fingerprinting, a gel-like fluid is used to distinguish between DNA molecules that move at various speeds. A DNA molecule that is huge moves slowly, whereas a DNA molecule that is little moves quickly.
Therefore, DNA molecules are divided in gel electrophoresis according to size. When DNA molecules are divided into distinct sizes, bands of DNA are created.

Leukemia is a malignant progressive disease in which the bone marrow and other blood-
forming organs produce increased numbers of immature or abnormal white blood cells.
Which statement about cell cycle checkpoints describes how this disease occurs?
A Dysfunctional checkpoints may lead to abnormal cell growth.
B Defective checkpoints result in death of a cell.
C Normal checkpoints assess damage to cancer cells.
D Cell checkpoints fail only in meiosis.
What would this be.
Answer:
A Dysfunctional checkpoints may lead to abnormal cell growth.
Explanation:
One of the hallmarks of cancer is unregulated cell proliferation. This means cells keep dividing, producing large numbers of often abnormal cells.
There are many of ways this can happen, such as increased signals telling the cells to divide, and dysfunctional cell cycle checkpoints that do not stop the cell from dividing. This leads to the accumulation of mutations and abnormal cell growth.

Which form of precipitation would you predict when you see a cloud shaped like a column in the sky during the summer at an above freezing temperature? (2 points)
Group of answer choices:
Heavy rain and hail
Light rain, sleet, and snow
Heavy snow and strong winds
Clear skies with no precipitation
Answer:
light rain sleet and snow
A)
Column shaped clouds usually mean that heavy precipitation is on the way.
A fair amount of the world's precipitation falls as snow or some other solid water form. Actually, outside the tropical regions, it is likely that the much of the precipitation begins in the solid form and only becomes liquid rain when it melts while falling through air with temperatures above freezing.

A famous celebrity has an extreme security system for their estate. The security system includes sensors in the ground as well as on the sides of the buildings. A loud truck drives down the road entering the estate. There is a sensor in the ground and another on the side of the security guard’s shed. If both sensors are 100m from the truck, which sensor will pick up the noise of the truck first and why?
A.
Guard Shed - The sensor on the security guard’s shed will detect the sound first because the sound is traveling through the air and sound will travel fastest through a gas.
B.
Ground - The sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through a solid.
C.
Same time - Because the sound is traveling through both the ground and the air at the same time, it will reach both the shed and the ground sensor at the same time.
D.
Neither sensor - 100m is too far for the sound to travel. Neither sensor will pick up the sound of the truck until it is closer to them.
Answer:
B. Ground - The sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through a solid.
Explanation:
Sound wave is an example of mechanical wave, which means sound waves require a medium to travel through. However, how fast a sound travels is dependent on the kind of medium it travels through. Sound travels fastest via a SOLID medium, then liquid and slowest through gases.
According to this question, sensor in the ground and side of the security guard’s shed were placed in an estate owned by a famous celebrity. A loud truck, then, drives down the road entering the estate.
Based on the principles of sound eaves movement, the sound from the truck will be picked by the sensors in the GROUND first because the sound is traveling through the dirt and sound will travel fastest through a solid.

(Environmental) Southern England What are the major concerns about soil erosion on arable land in Britain?
Answer:
Soil nutrient loss
Algae blooms
Pollution of water ways
Explanation:
Soil nutrient loss - a major concern as when soil erodes, this results in nutrient run off. Heavy rains can "wash away" essential nutrients within the soil therefore reducing the fertility of the land.
Algae blooms - when nutrients run off soil as a result of soil erosion they can leech into nearby fresh stream and even into salt water marine environments. This large increase of nutrients results in algae thriving and forming a layer across the top of the water. This reduces the oxygen and sunlight available to other marine plants and essentially suffocates plant and animal species.
Pollution of water ways - The sediment of soil that is eroded makes its way into fresh water ways can not only "bury" plant species and reduce biodiversity but it also reduces the water quality. It can introduce pathogens to the water from liverstock farming as well as introducing pesticides that may be harmful to wildlife.

Explanation:
Every single cell organism is able to survive because it carries out
Every single cell of an organism is able to survive independently because it carries out metabolic processes at its own.
What is Metabolism?Metabolism can be defined as the chemical changes or reactions which take place in a cell or an organism. These changes make energy and the compounds which cells and organisms need to grow, reproduce, and stay healthy.
Metabolism is divided into two classes: anabolism and catabolism. Anabolism involves the synthesis of a complex compound from simpler or smaller molecules or atoms. Catabolism involves the breakdown of a complex molecule into smaller and simpler ones.
Living organisms are able to perform the metabolic processes such as respiration, excretion, reproduction, and digestion which is a distinguishing factor from that of non-living organisms.
