Answers
Answer:
The answer is C
Explanation:
I was correct at first but then chanaged my answer when someone said it was a :(
A few of the positive particles aimed at a gold foil seemed to bounce back off of the thin metallic foil. Therefore, option (1) is correct.
The gold foil or Rutherford scattering experiment showed that the atom has a small, compact, positively charged nucleus. The gold foil deflected few alpha particles, indicating that the atom is primarily empty space. A small percentage of particles deflected or bounced back, revealing a concentrated positive charge in a limited region of the atom.
This led to Ernest Rutherford's atomic model, often known as the planetary model, where the atom has a tiny, positively charged nucleus at the centre and mostly empty space where electrons orbit it. Therefore, option (1) is correct.

What molecules are inputs in photosynthesis
Answers
Water, carbon dioxide, and sunlight-derived energy are the inputs and glucose and oxygen are the products of photosynthesis.
What is photosynthesis?Plants and other creatures use photosynthesis to transform light energy into chemical energy for cellular respiration and activity.
Photosynthesis draws CO2 and H2O from the air and soil. The plant cell oxidizes water and reduces carbon dioxide. Water turns oxygen and carbon dioxide into glucose.
Photosynthesis stores chemical energy from solar radiation. This process powers most of Earth's life systems.

Since oxygen gas is being released, it can be inferred
that the plant is
A. producing glucose
B. releasing energy from water
C. making protein
D. carrying on active transport
Answers
Answer:
Option A
Explanation:
The answer is option A or "producing glucose." Glucose is a sugar that is a main component for all living organisms because it contains carbohydrates. When oxygen is being released from a plant it means that it's producing glucose which is released through the plants stomata.
Hope this helps.
Since oxygen gas is being released it can be inferred that the plant is PRODUCING GLUCOSE. (Option A).
Photosynthesis is a series of metabolic reactions by which plants and algae use the energy from the sun and carbon dioxide to produce simple carbohydrates (e.g., glucose) and oxygen.
Photosynthesis has two main types of reactions: light-dependent reactions and light-independent reactions (i.e., the Calvin cycle).
During light-independent reactions, carbon-containing molecules such as, for example, glucose molecules, are produced from carbon dioxide.
In conclusion, when oxygen gas is being released it can be inferred that the plant is PRODUCING GLUCOSE (Option A).

2) The position and time do not change, therefore it is not moving
3) The position and time are moving, but at a constant speed.
Object's motion with the position-time graph that represents at:

2) C
3) B
What do you mean by motion of an object?Motion is the phenomenon in which an object changes its position with respect to time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed.
Moreover, the free movement of a body with respect to time is known as motion. For example-the fan, the dust falling from the carpet, the water that flows from the tap, a ball rolling around, a moving car etc. Even the universe is in continual motion.
Therefore, it is a change of position or orientation of a body with the change of time. Motion along a line or a curve is named translation. Also, the motion that changes the orientation of a body is rotation.

Answers
The diagram shows the process of transcription of gene for making proteins.
The diagram shows a process that occurs in eukaryotic cells is transcription of gene for making proteins because the diagram represents the structure of DNA. Transcription is the process of making an RNA copy of a gene sequence. This copy is known as messenger RNA (mRNA) molecule.
This messenger RNA leaves the cell nucleus where it is produced and enters the cytoplasm where it directs the synthesis of protein which it encodes so we can conclude that the diagram shows the process of transcription of gene for making proteins.

What is the process by which food produced in
photosynthesis is transported from the leaves to
the growing regions of plants and storage
organs?
Answers
Answer:
Translocation
Explanation:
Biosynthesis of carbohydrates in green plants is called photosynthesis. This proces uses inorganic carbon (CO2), water and solar energy in a complex, multi-step process in mesophyll cells of leaves (sources).
Afterward, plants optimize the reaction products for use or storage in other regions. Plants form sucrose, as an energy-efficient storage molecule for transportation and later storage.
Sucrose contains more energy than the monomer, glucoseSucrose is a highly stable non-reducing sugar- it is non-reactive.These sugars move through the mesophyll via plasmodesmata; here, they reach phloem sieve tube elements in vascular bundles. From the STEs, they are actively transported against their concentration gradient to the phloem.
When the sugars enter the phloem, their high concentration cause water to move into the phloem from neighboring xylem vessel. This increases the water pressure inside the phloem, causing the sap to move towards sinks. Sinks may be actively growing regions or storage like the roots. There, the sucrose is polymerized into starch for long term storage.

Rachel is a forensic investigator. She checks for lividity in the body of a dead victim. What does she know about the cause of lividity?
Rachel knows that
causes the blood to pool to the parts of the body closest to the ground after death.
Answers
Answer:
The answer is Gravity my guy
Explanation:
Finished my Forensics semester with a 98% and I'm currently studying to be a Forensic Anthropologist.
Gravity is the cause of lividity, which causes the blood to collect in the bodily parts closest to the ground when a person dies.
What is lividity?The process through which the body's blood ceases flowing after death as the heart stops pumping is known as livor mortis.
Gravity causes the blood to start settling to the lowest portions of the body, where it congeals and stays even if the body is moved.
Rachel is aware that when someone dies, the blood tends to collect in the body parts that are closest to the ground.
The bodily parts that are closest to the ground or a surface when someone dies are considered to be the lowest portions. The dead person now becomes pale, and the lividity region turns purple or reddish-purple.
Therefore, gravity causes the blood to start settling into the lowest portions of the body.
