consisting of two protons and two neutrons emitted by radioactive materials we get what is called a alpha particle
they are usually formed when identical to the nucleus of the helium-4 atom are emitted by radioactive matter !
What can they do to the body?
Since they have radioactive material in them they are very DANGEROUS! If they are inhaled swallowed or somehow get inside our bodies it can cause serious harm!They can harm sensitive living tissue and can go as far as to causing cancer !
What is their electric charge?
+2 e
What is their symbol ?
α, α2+, He2+
Hope this helps!

Describe fertilisation in terms of cellular and intracellular changes. I will be very happy if someone answer this I will give them brainly and likes
Answer:
during this process the nucleic of the male and female gametes are fused in order to create a zygote .known as fertilisation.Gametes contain half the number of chromosomes of all other cells in the organism .Meaning they are haploid .
Cells responsible for fertilisation:
fertilisation is the fusion of the nucleus of a male gamete with the nucleus of a female gamete ,producing a new cell called a zygote

which statement best describes the organization of the taxa shown in the image
A. as you move down the structure, the groups become more general
B. there are more organisms in each group as you move down the structure
C. as you move up the structure the group becomes more specific
D. as you move down the structure, there are fewer organisms in each group
Answer:
D. as you move down the structure, there are fewer organisms in each group.
Explanation:
When we move down from kingdom to species, the number of organisms decreases because more closely related organisms are placed down the group. There are fewer kingdoms that have a large number of organisms in it and has less similarities among them and when we move down, the number of organism decreases in number and at the end there are few organisms are present in it which is more closely related to each other.

Which student’s answer describes and explains an internal adaptation that allows for a specific function?
Explanation:
As internal adaptation refers to anatomical adaptation so correct option is B - Student 2: Birds have hollow bones, enabling them to fly.
The bones of birds have hole openings inside. Therefore, chicken bones are much less dense than human bones. These hole areas purpose the chicken to have lighter mass, permitting a less difficult raise for flight. Birds additionally have air sacs which can be extensions of their lungs. Hollow bones also are referred to as pneumatized bones, which means they may be full of areas for air. It is the notion that this shape allows for oxygen consumption throughout the flight. Air sacs are connected to the hole regions in a chicken's bones.What is the use of feathers?Birds have feathers that assist them to fly. The lengthy flight feathers at the wings and tail assist birds' stability and steering. In addition, birds have a device of air sacs of their frame that hook up with the lungs. The air sacs permit birds to extract plenty greater oxygen from every breath of air than different animals can.
Thu it is clear that birds have hollow bones, enabling them to fly is an internal adaptation.

In recent years, scientists and the public have raised a number of ethical and legal questions about DNA. Many of the questions involve issues of ownership and privacy of personal genetic information. Issues like these became relevant to society because which of these scientific achievements?
ANSWER: The completion of the Human Genome Project
EXPLANATION:
Human Genome Project (HGP) was completed in April, 2003. Genome varies from one individual to another.
The project involved mapping and sequencing of some people and in other to get each chromosome full sequence in individuals.
However, at the beginning of this project, concerns like ownership and privacy of personal genetic information began to spring up. People are afraid that employers may have access to their genetic information and would reject persons with health issues indicated by their unique genes and health insurance companies may also not provide insurance to people that have deficiency.
In the view of this concern, the United States in 1996 passed the Health Insurance Portability and Accountability Act (HIPAA) which guides against the non-consensual and unauthorized release of health information of individuals.

A scientist observes a geyser erupting. Which two objects must be interacting beneath the surface?
O well and spring
O spring and magma
O magma and groundwater
O groundwater and unsaturated zone
Answer:
c
Explanation:
Magma and groundwater are responsible for the eruption of geyser.
GeyserGeyser eruptions are as a result of the conversion of thermal to kinetic energy during decompression.
When the groundwater deep in the ground is heated up by magma, pressure is released and the water will erupt out of the ground as a geyser. Eruptions occur about every 50-100 minutes.
