C. 69.3 g
D.950 g
Answers
Answer:
96.5g
Explanation:
Given parameters:
Volume of Au = 50cm³
Density of Au = 19.3 g/cm³
Unknown:
Mass of the gold = ?
Solution:
Density is the mass per unit volume of a compound.
Density = [tex]\frac{mass}{volume}[/tex]
Mass = density x volume
Insert the parameters and solve;
Mass = 19.3 g/cm³ x 50cm³ = 96.5g

The diagram shows a reflex arc. Name parts P and Q shown on the diagram above.
Please help.
Answers
Answer:
P - synapse
Q - Relay neuron
Explanation:
A synapse, easy to remember as a neural junction, is the site where the transmission of electric impulses occurs. This occurs between two neurons or between a neuron and a gland or muscle cell. So in this scenario when we poke the finger it fires an electric nerve impulse that gets to the P spot that is a synapse and gets transmitted to the relay neuron. A relay neuron is there to receive the signal from one neuron and then transfer it to another interneuron resulting in the signal being received by a motor neuron so that we can react to the stimulus.

During an experiment to determine if people with more symmetrical body features have a lower incidence of disease, a researcher first measures the length of several bones in the subject's hands and arms. The device used to measure length does not display a readout of the measurement taken. Instead, a wire connects the measuring device to a computer that records the data. The computer monitor is kept out of sight of the subject and the researcher. Why is such an elaborate device used?a. So that the subject will not know if he or she is part of the control group.b. So that the experiment will be repeatable.c. So that the subject will not be injured by the experiment.d. So that the identity of the subject will remain anonymous.e. So that the measurements are not biased by the researcher.
Answers
Answer:
e
Explanation:
The main reason such an elaborate device was used would be to eliminate any element of bias by the researcher.
It is important to eliminate biases when taking measurements so as to ensure the accuracy of the data and the overall outcome of the experiment. If a simpler device had been used in which the researcher manually records the length of the bones, it is possible to knowingly or unknowingly introduce biases or random error into the experiment which will impact the integrity of the data and the outcome of the experiment.
The correct option is e.

Answers
Answer:
C. The salt is dissolved by the water
Explanation:
When ionic compounds dissolve in water, the individual ions separate and get surrounded by water molecules—a process called solvation. Because the salt ions are charged, they dissolve much better in a polar solvent, which is also slightly more charged than a nonpolar solvent

Which of the following is true regarding tissue?
a)
An example of tissue is the digestive system, which helps break down food
particles for organisms to obtain energy and nutrients.
Ob) Tissue is a group of specialized cells that work together for a common
function and form organs.
O c) Sponges are the only animal made of tissue and made of haploid cells.
d) Tissue is a group of diploid molecules bonded together chemically.
Answers
Answer:
True: b) Tissue is a group of specialized cells that work together for a common function and form organs.
Explanation:
Cells are the smallest units of life, they may be either unicellular or multicellular. Unicellular organs have a single cell capable of carrying out all of the functions necessary for its survival. Multicellular organisms are more complex, and require the work of multiple different cell types.
Their cells become differentiated- where they undergo certain processes to become specialized, and gain maturity. Groups of specialized cell types form tissue; these each have varying functions over time. Organs consist of two or more tissue types that are specifically organized to carry out a function.
Answer:
b) Tissue is a group of specialized cells that work together for a common
function and form organs.
Explanation:
Sponges are the simplest type of animal therefore they have a few different features than other animals. Like all animals, sponges are diploid, multicellular, heterotrophic, reproduce sexually, mobile, and don't have a cell wall. They are different in that their zygotes do not form into a blastula and they are not made of tissue.

How can DNA be used to help solve a crime?
Answers
Answer:
Each person’s DNA is unique.
Scientists use variable regions in DNA to create a DNA profile.
DNA samples can be taken from blood, bone, hair, or other body tissues and
products.
DNA from a crime scene can be compared to DNA from a suspect.
DNA typing can be used to solve old cases.
Explanation:
edge 2021
DNA can be used to solve a crime as the sample of the DNA of a person can be compared to the evidence that's gotten from a crime scene.
Deoxyribonucleic acid which is commonly referred to as DNA is the molecule that has all the information that's vital to build an organism. Each person’s DNA is unique.
DNA contains the genetic information of everyone. DNA samples can be taken from blood, bone, hair, or other body tissue.
To solve a crime, DNA from a crime scene can be compared to DNA from a suspect. If the DNA collected is the same as the one that's seen at the crime scene, then it shows that the person is responsible for the crime.

Which of these organisms would most likely be found at the top of an energy pyramid?
a clams - a primary consumer
b. sardines - a primary consumer
c. sharks - a secondary consumer
d. kelp - a primary producer
Answers
The energy pyramid is a diagram that shows the flow of energy between trophic levels in an ecosystem. In an energy pyramid, the energy flows from producers to consumers.
The organisms that would most likely be found at top of the energy pyramid are sharks (secondary consumers).In an energy pyramid, the energy flows from producers (e.g., plants) to primary consumers (eg., herbivores). Subsequently, the energy then flows from primary consumers to secondary consumers (e.g., carnivores) and so successively.In an energy pyramid, the amount of available energy decreases as it moves through subsequent trophic levels.In conclusion, the organisms that would most likely be found at top of the energy pyramid are sharks (secondary consumers).

Recall what you know about nervous tissue to answer the following questions. Nervous tissue can generate and conduct ____ signals that control the body.
answer choices are:
chemical
electrical
thermal
Answers
Answer:
Nervous tissue can generate and conduct electrical signals that control the body.
Explanation:
The neuron is the specialized cell that provides function to nerve tissue. Given the structure of the neuron, this cell is capable of creating and conducting information in the form of electrical impulses or signals, by depolarizing its cell membrane and generating action potentials.
The information generated and transmitted by the neurons allows the nervous system to obtain internal and external information of the organism, as well as to control all the body functions.
The other options are not true because nerve tissue does not generate or conduct thermal or chemical signals to perform its function.

Besides helping to discover the structure of DNA, describe two other contributions Rosalind Franklin made to the world of science.
Answers
Answer: Rosalind Franklin discovered the density of DNA and, more importantly, established that the molecule existed in a helical conformation. Her work to make clearer X-ray patterns of DNA molecules laid the foundation for James Watson and Francis Crick's suggestion that DNA is a double-helix polymer in 1953.
Explanation:
Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.
What is the contribution of Rosalind Franklin?She was one of the greatest scientists who made significant contributions to the field of DNA by using X-ray crystallography, and apart from that, she also made contributions to the field of virology. As X-ray diffraction facilitates the study of the structure of viruses such as the tobacco mosaic virus and the polio virus and helps in understanding the replication of viruses, it is also helpful in the study of the structure of coal and other carbon-based materials.
Hence, Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.
