PLZ ANSWER IN OWN WORDS Why do the bone structures around your head and chest create a convex, enclosed area, unlike the bones in your arms and legs?
Answer:
Bones have different shapes depending on their structure. In the case of the head and the chest, these flat bones protect organs such as the brain and the heart. On the other hand, long bones support the body's movement.
Study the pedigree chart. ( picture above)
Which of these can be determined about the trait based on this chart?
○ The trait is recessive. the parents of A were both carriers
○ The trait is recessive. The parents of A were both affected
○ The trait is dominant The parents of te were both affected.
○The trait is dominant The parts of A were both carriers
Answer: The trait is recessive. the parents of A were both carriers
Explanation: The correct answer should be the trait is recessive.
Since we can only see A mothers tree and she is not affected by the trait she is a carrier.
Unfortuately, the tree does not show her father's side of the tree so we can only "assume" based on the options that he also is a carrier of the trait.
So answer it will be "The trait is recessive. the parents of A were both carriers"
Kim's Dalmatian, Tigger, always eats the same brand of food. Although he does everything else at lighting speed, he is a very slow eater. After watching a TV commercial touting the irresistible taste of Puppy Yums Dog Vittles, Kim decides to conduct an experiment comparing Tigger's regular food (K-9 Crunchy Bits), Puppy Yums Dog Vittles, and a store brand that cost 1/3 as much as the advertised food. Kim gave Tigger the same quantity of each different food, on three successive evenings, and used a stopwatch to determine Tigger's dinner-time munching speed.
Hypothesis:
Predicted Results:
Independent Variable:
Dependent Variable:
Control Variable:
The experiment was intended to show that the dog will eat the tastier food advertised on TV at a faster rate than it eats its regular food.
An experiment must have an independent variable and a dependent variable. The dependent variable is the variable that is being manipulated in the experiment. The responding variable is also called the dependent variable.
In this experiment;
The independent variable is the type of dog foodThe dependent variable is the eating time of the dogThe predicted result is that the dog will eat the advertised Puppy Yums Dog Vittles faster than the other dog foodsThe control variable is the quantity of dog food given to the dog each evening.The hypothesis of the experiment is that the dog will eat the advertised tasty food faster than it eats its regular food.Learn more: https://brainly.com/question/22824409
Where does cell respiration and fermentation happen in cell?
Answer:
Mitochondria
Explanation:
At this point, 6 carbon dioxide molecules have
been released (2 from the link reaction and 4
from the Krebs cycle). Why does this make
sense?
Glucose has combined with oxygen to make carbon dioxide.
Glucose has 6 carbons and has been completely broken down by this stage.
The 6 carbon dioxides are reactants that will be used to make ATP.
These 6 carbon dioxides are converted to oxygen by respiration.
All of these.
Glucose has combined with oxygen to make carbon dioxide and Glucose has 6 carbons and has been completely broken down by this stage.
Glucose react with oxygen to make carbon dioxide, water and energy in the form of ATP. Glucose has 6 carbon atoms which react with oxygen that is completely broken down into three products such as carbondioxide, water and energy in the form of ATP by the process of cellular respiration so we can conclude that carbondioxide gas is produced by breaking down of glucose molecules from the Krebs cycle that is a stage of respiration.

How were ozone levels monitored in 1920?
Answer:
I don't know
Explanation:
Sorry.. I really don't know

Help you later
Ozone levels in 1920 were primarily monitored using chemical methods, such as the use of chemical indicators and colorimetric analysis.
Potassium iodide-starch paper was used to detect ozone. When exposed to ozone, these indicators changed colour, letting researchers visually monitor ozone concentration.
Colorimetric analysis was also used. Chemical reagents reacting with ozone changed colour. Ozone concentration connected with colour change intensity. Chemical approaches measured ozone qualitatively or semi-quantitatively. They were easy to use but less precise than modern monitoring approaches.
In the following decades, spectrophotometry and ozone analyzers improved the systematic monitoring and quantitative measurement of ozone levels. These improvements made atmospheric ozone monitoring more precise.

When Mendel conducted his pea plant genetic experiments, he found that the first generation (F1) of offspring were all true purple plants, but the second generation (F2) contained some white flowers. How did this refute another theory of inheritance based on the idea that traits in offspring were an equal mix of the traits of their parents?

Which cell type undergoes terminal differentiation?
Stem cells are the only form of cell that can differentiate into more specialized cell types. Therefore, they undergo terminal differentiation.
What is terminal differentiation?As cells migrate to the surface and fully differentiate, i.e., as they keratinize and eventually die, this process is known as terminal differentiation. Terminal differentiation is a method of describing that the cells change their phenotypic traits.
During the process of terminal differentiation, several cell types (such as neurons, skeletal and cardiac myocytes, adipocytes, and keratinocytes) acquire specific tasks and ultimately exit the cell cycle. This process may be observed in neurons, adipocytes, and keratinocytes.

why is it necessary for scientists to use clues from celestial objects to determine the age of our planet?
Answer:
Meteorites, which are the very components of our planets (through the process of accretion), are the remnants of the Solar System's origins. Dating meteorites thus allows us to give a lower age to the Solar System (4,56 billion years old).
