Which of the following is true about subatomic particles?
The mass of a neutron is equal to the mass of a proton
Neutrons have no charge and are the lightest subatomic particle
Electrons are negatively charged and are the heaviest subatomic particle
Protons are positively charged and the lightest subatomic particle
Answer:
Neutrons have no charge and are the lightest subatomic particle
Explanation:
Nucleus of an atom contains three subatomic particles. These are protons, neutrons and electrons.
Mass of a proton is [tex]1.67[/tex]×[tex]10^{-27}[/tex]kg.
Mass of a neutron is [tex]1.67[/tex]×[tex]10^{-27}[/tex]kg.
Mass of an electron is [tex]9.1[/tex]×[tex]10^{-31}[/tex] kg.
Also, protons are positively charged, neutrons have no charge and electrons are negatively charged.
Therefore, we can conclude that the mass of a neutron nearly equals the mass of a proton.

What happens to most of the precipitation that
falls on land?
a. It evaporates.
c. It seeps into the ground.
b. It becomes runoff, d. It becomes glacial ice.
Only about a third of the precipitation that falls over land runs off into streams and rivers and is returned to the oceans. The other two-thirds is evaporated, transpired, or soaks (infiltrates) into groundwater. Surface runoff can also be diverted by humans for their own uses.

How do igneous
rocks form?
a. compaction and cementation of sediment
b. heating and added pressure to existing rock
c. evaporation of seawater
d. cooling of molten lava or magma
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.
Answer:
cooling of molten lava or magma
Explanation:
ICM.06] Scientific research shows that our global climate is changing as a result of an increase in greenhouse gases. Arctic sea ice is decreasing in both surface area and thickness. Which of the following statements best describes the
consequence of decreasing Arctic sea ice?
The melting of sea ice will decrease the effects of global warming in the area as the ice absorbs heat
O seawater levels wil decrease making t difficult for marine animals to survive.
Animals that rely on the sea le for survival may become extinct as their habitat disappears.
The milder temperatures will allow for greater survival rates for native species
As a result of decreasing Arctic sea ice, animals that rely on the sea level for survival may become extinct as their habitat disappears.
The increase in the atmospheric greenhouse gases means that more radiant energy from the sun that could have escaped back into space is being absorbed, leading to an increase in the global temperature.
The increase in the global temperature means that more Arctic sea ice would be melting and decreasing in size. As the ice melts, the water moves into seas thereby causing a rise in their levels.
A rise in sea level means the disappearance of coastal habitats. Thus, a loss in biodiversity will occur as the habitats of plants and animals disappear as a result of the rise in sea levels.

Which statement correctly describes fertilization? (1 point)
Fertilization is the process in which the zygote undergoes mitosis and forms a group of cells.
O Fertilization is the process in which male and female gametes fuse and form a fertilized egg.
Fertilization is the process in which the embryo develops a fluid-filled sac for protection.
O Fertilization is the process in which male and female gametes shift to align with the birth canal.
Answer:
B
Explanation:
Fertilization is the process in which male and female gametes fuse and form a fertilized egg. The correct option is B.
What is the process of fertilization?During fertilization, sperm and egg combine to form a zygote in one of the fallopian tubes.
The zygote then travels down the fallopian tube and develops into a morula. The morula develops into a blastocyst once it reaches the uterus.
The blastocyst then burrows into the uterine lining, which is referred to as implantation.
The sperm binds to the secondary oocyte via the corona radiata, a layer of follicle cells on the outside of the oocyte.
Fertilization is divided into three stages: sperm capacitation and acrosome reaction, sperm-egg binding and fusion, and cortical reaction and oocyte activation.
In a nutshell, sperm capacitation takes place in the female genital tract and prepares sperm cells for the acrosome reaction.
Thus, the correct option is B.

Which of the following is a type of polar attraction?
A A metalic bond
8. A hydrogen bond
C. An ionic bond
A covent bond
Answer: A) Hydrogen Bond
Explanation:
A hydrogen bond occurs when a hydrogen (H) is covalently bound to a more electronegative atom or group forms an electrostatic attraction to another electronegative atom bearing a lone pair of electrons. This is possible due to the polarity of the H-electronegative atom bonds.
The basic building block of matter
Answer:
Scientists once thought the most fundamental building block of matter was a particle called the atom. Now we know that the atom is made of many smaller pieces, known as subatomic particles. Every atom contains a central core called the nucleus, made of particles called protons and neutrons.

Which characteristic best explains why lentic ecosystems are more responsive to seasonal changes than lotic ecosystems?
Photosynthetic organisms keep lentic ecosystems warmer during the winter season.
Lentic ecosystems are susceptible to temperature due to their low dissolved oxygen.
Lotic ecosystems have low nutrient levels, making them more sensitive to temperature.
Lentic ecosystems tend to have smaller volumes of water compared to lotic ecosystems.
Lentic ecosystems tend to have smaller volumes of water compared to Lotic ecosystems.
Lentic ecosystem consists of still (stagnant) volume of water and good examples include ponds,lakes, basins etc.
Lotic ecosystem , on the other hand consists of a flowing volume of water and examples include seas, oceans, rivers etc.
The Lentic ecosystem usually is usually still and is affected by seasonal changes as it contains smaller volume of water when compared to the Lotic ecosystem which has a high volume.
Seasonal changes such as summer or winter affects the Lentic system easily as the small volume of water gets heated up and frozen easily which encourages more evaporation and freezing respectively.

The cell membrane of an animal cell was damaged, preventing the cell from performing one of its functions. Which cell function would be lost, and how would this loss affect the cell?
Answer:
ok so
Explanation:
If the cell membrane of an animal cell is damaged, it would lose the ability to take in nutrients and excrete wastes. This would hinder the cell's capacity to create necessary materials and maintain proper functioning. Thus, the correct option is (b).
The correct response is option (b). The transport of chemicals into and out of the cell is regulated by the cell membrane, which acts as a selectively permeable barrier. Essential cell processes like food intake and waste elimination would be impeded if the membrane were to get disrupted.
This would impede the cell's capacity to produce required components through nutrient-dependent processes like metabolism. There would be a significant negative impact on the cell's general health and function, which could result in cellular malfunction, slowed growth, and ultimately cellular death.
