Answer:
The plants that were allowed to self pollinate were the First filial generation, filial, Latin for family. Or just the F1 generation plants.
The plants that are true breeding are Parental generation or for shorthand, the P generation plants.
The plants where there were three times as many tall plants as short plants are in the second filial generation, or the F2 generation.
This question is based on the Mendel’s Experiment.
Sir Gregor Johann Mendel.
Mendel experimented on pea plants and gave the laws for genetics which are a very important aspect of hereditary. Because of his experiment the terms recessive and dominant came into light and how the genes are passed from generations were also studied.
The statements can be completed as:
Plants that were allowed to self pollinate were F1 or the first filial generation.The true-breeding plants are P (parental) generation.The plants having the phenotypic ratio of 3:1 for tallness and shortness are in F2(second filial) generation.The steps can be explained as:
The cross which is the first step between the given alleles of a trait in a cross is called parental (P) generation.The progenies produced as a result of a cross between the parental traits is called the first filial (F1) generation.When the traits from the F1 is interbred then a second filial generation (F2) is produced.To learn more about parental and filial generations follow the link:

What type of cells reproduce by mitosis
In mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells, same number chromosomes.
What is chromosome ?
A chromosome is defined as a thread-like structure present in the nucleus of cells such as both prokaryotic and eukaryotic cell and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.

what are the scientist doing incorrectly? what could they do to make their work in the lab safer? why is it important to follow these procedures? part c
Answer:
What the scientist is doing incorrectly is placing test tubes in a cabinet in disorderly form, without protective or biosafety equipment, having other tubes loose on the shelf, which can fall, break and spill their contents.
Explanation:
The image scientist is doing an incorrect procedure because
He is handling laboratory material without protection. He has messy tubes on the shelf of the cabinet, which can be chewed and broken, spilling their contents. He is not using a ladder to reach the highest spaces in the cabinet and place the tubes.What could they do to make their work in the lab safer?Use biosafety equipment to handle containers with chemical or biological substances.Keep the tubes in racks or tube holders to prevent them from falling accidentally.Place the tubes in an orderly manner, using a ladder to place the tubes at the top of the cabinet.Why is it important to follow these procedures?It is important to follow these procedures to protect his body from accidental spills, as well as to avoid breaking containers and contaminating the work space.

The tongue is an example of an organ that assists in the process of digestion. which of the following best describes the level of structural organization for organs like the tongue?
A. It is less complex than a tissue
B. It is more complex than an organ system
C. It is less complex than a cell
D. It is more complex than a tissue
Answer:
C
Explanation:
The level of structural organization for the tongue is that it is more complex than a tissue. So the correct option is D.
What is a tongue?
In most vertebrates, the tongue is a muscular organ on the floor of the mouth that may move in a variety of ways. It is extended and specialised in grabbing insect prey in some animals (like frogs).
While cats and certain other animals use their tongues as tools for grooming and cleaning, some reptiles' tongues serve largely as sensory organs.
The tongue is an essential auxiliary organ in chewing and swallowing, helps mammals create negative pressure in the oral canal to permit sucking, is a key carrier of taste receptors, and helps humans speak.
The mammalian tongue is formed of a complex of striated, intertwined muscles, fat, and glands, all coated in mucosal surfaces. Humans often have their front tongue ends and margins in contact with their teeth, which facilitates communication and swallowing.
Therefore the correct option is D.

This transportation process requires the cell to move particles from low concentration to high concentration. active transport facilitated diffusion osmosis diffusion
Answer:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

Some transcription signals are located thousands of base pairs upstream of the gene they regulate. How does the distant signal initiate transcription
Answer:
enhancer sequences bind to transcription factors to increase the likelihood of transcription
Explanation:
Enhancers are short DNA regions (50–1000 bp) that may be localized upstream and downstream from the transcription start sites of the gene. It has been shown that enhancers can be localized several kilobases (30-100 kb) either 5' or 3' of the gene. These sequences bind to proteins (generally transcription factors) in order to alter the 3D structure of the DNA, thereby increasing the likelihood of transcription.

O Since menopause, Sarah's levels of the hormone testosterone have increased
O Since menopause, Sarah's levels of the hormone estrogen have increased.
O Since menopause, Sarah's levels of the hormone testosterone have dropped.
O Since menopause, Sarah's levels of the hormone estrogen have dropped.
Answer: Since menopause, Sarah's levels of the hormone estrogen have dropped.
Explanation:
The most likely cause of injury in the following scenario is that because of the menopause, Sarah's levels of the hormone estrogen, which is also known as a female hormone, have dropped and because of that she is playing ice hockey with others and since she did not play it before, she broke her elbow.
She broke it because she was inexperienced with it and if she has played it before menopause she could not break it.

24
Explanation:
10x + y = 4(x + y) Remove the brackets
10x + y = 4x + 4y Subtract 4x from both sides
10x - 4x + y = 4x - 4x + 4y Combine like terms
6x + y = 4y Subtract y from both sides
6x + y - y = 4y - y Combine
6x = 3y Divide by 3
6x/3 = 3y/3
2x = y
Put this result in the equation below
x*y = 8
x(2x) = 8
2x^2 = 8 Divide by 2
2x^2/2 = 8/2
x^2 = 4 Take the square root.
√x^2 = √4
x = ± 2
y = 2*x = ±4
Answer
The plus answer for x and y is the one we'll see about first.
10x + y = 20 + 4 = 24
24 =? 4(2 + 4)
24 =? 4*6 = 24
The product of it's digits = 2 * 4 = 8.
24 is definitely one answer.
========================
What about -2 and - 4
-24 = 4(-2 + -4)
-24 = 4*-6 = -24
That works as well
