4. If you are male, which member of your family should you look at to tell whether you are going to
go bald? Why? Use a punnett square to prove your answer.
Answers
Answer:
Your mother
Explanation:
If you are a male, the member of the family you should look at to tell whether you are going to go bald is your mother.
Baldness is a sex-linked recessive trait and as such, the two X chromosomes in females need to carry the allele in order for females to be phenotypically affected for the disorder. The males having only one X chromosomes however, means that they only need that single X chromosome to carry the baldness allele in order for them to be affected for baldness.
Assuming the allele for baldness in represented by b. Your mother is affected for baldness while your father is free from the disorder. This means that the genotype of your mum would be \(X^bX^b\) while that of your dad would be \(X^BY\). According to law of inheritance, males usually inherit their X chromosomes from their mother. This means that any male your mother gives birth to would have the genotype \(X^bY\) which phenotypically means that they will be affected for baldness.
The attached image shows the Punnet's square analysis of what will happen during inheritance.

explain the difference between gills and lungs. Give examples of animals that have only gills, animals that have only lungs, and animals that have both gills and lungs. What are the advantages of having gills, having lungs, and having both?
Answers
Answer:
Gills and lungs differentiate in many ways most certainly when it comes to breathing. Gills are used by aquatic animals such as; sharks, fish and octopi. Lungs on the other hand are mainly used by mammals such as; humans, dogs and hamsters.
Lungs help breathe in air for oxygen and gills help breath in the oxygen contained in the water.
There's many advantages you could have with breathing through gills and lungs, you could swim under water for much longer periods of time and you could obviously walk on land and easily breath the air.
Sorry this took so long to write, I do hope this helped!
Good luck!
Lungs : are used to breath above water
Gills eg: fish
Lungs eg: human’s, lions etc
Animals that have both gills & lungs eg: frog , lungfish etc
Advantages are
Having lungs : can breathe on land
Having gills : can breath in water
Having both : can breath on land and in water

Compare an elephant’s trunk with a person’s hand. How are they similar? How are they different?
Answers
Answer:
one way that they are different is that unlike us humans they don't have fingers on their trunk. one way that they are similar is that both use something to pick objects up.
Explanation:
hope this helps you!
Both the elephant trunk and human hands are used to grasp objects.
The Elephant's trunk is the part of the elephant that extends outwards from its face and enables the elephant to pick up things. It is quite similar to the human hands in the sense that it can be used to grasp objects.
However, human hands are made of fingers but the trunk of an elephant is just a long structure that has no fingers. Hence, it is different from the human hands.

What best describes ribosomes?
Answers
Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.
Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.
An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.
Answer:
A ribosome is a intercellular structure made of RNA and protein

B. They can block the wind which can change the amount of precipitation that falls next to the mountain
C. They cause significant flooding around the bottom of the mountain.
D. They cause the land around the mountain to become very dry.
Question 2.
What factors influence climate? Select 3 that apply.
A. Population
B. Closeness to bodies of water
C. Ocean currents
D. Geographic location
Answers
Question 2: Answer: B. Closeness to bodies of water, C. Ocean currents, and D. Geographic location.
Explanations:
1. Mountains can create a barrier for wind and moisture, leading to different climatic conditions on the windward and leeward sides. The windward side usually receives more precipitation, while the leeward side is typically drier, creating a rain shadow effect.
2. Climate is influenced by a variety of factors, including closeness to bodies of water (which can moderate temperature and affect precipitation), ocean currents (which can distribute heat and impact regional climates), and geographic location (which determines factors like latitude, altitude, and proximity to landforms like mountains). Population is not a direct factor influencing climate, but human activities can indirectly affect climate through the emission of greenhouse gases and other pollutants.

A geyser shoots water and steam out of the ground. The hottest geysers heat steam to temperatures of 200°C or higher.
Volcanoes, geysers, and hot springs all provide clues about Earth's interior. They also show one of the ways that Earth's layers interact with each other.
1. What do you predict Earth's interior is like? How do its rocks compare to rocks on the surface? Cite evidence that supports your prediction.
Answers
The rocks are comparable to the surface because they are almost certainly metamorphic rock, which is supported by the fact that magma will melt and combine various types of rocks.
What geysers, hot springs, provide clues to Earth's interior?Hot springs and geysers are likewise created by heated underground water; hot springs are more frequent than fumaroles, while geysers are less frequent.
Geysers are created by a surface hole in the Earth's crust that stretches far below the surface. Water is put within the tube. Magma, which is molten rock towards the tube's bottom, heats the water there. Water in the lower portion of the tube near the magma gets extremely hot.
Therefore, Due to their sophisticated plumbing systems, geysers can be recognized from both hot springs and fumaroles, whereas a hot spring and a fumarole differ only in their level of warmth.

A boy has two slides to choose from at the park. One slide has a rough surface and the other one has a smooth surface. Which slide will he slide down faster?
He will travel faster on the rough slide because there is less friction.
He will travel faster on the rough slide because there is more friction.
He will travel faster on the smooth slide because there is less friction.
He will travel faster on the smooth slide because there is more friction.
Answers
He will travel faster on the smooth slide because there is less friction. The amount of friction between the slide and the boy's body affects how quickly he can slide down. The rough surface will create more friction, slowing down the boy's speed. The smooth surface will create less friction, allowing the boy to slide down faster.
Answer:
Option d
Explanation:
He will travel faster on the smooth slide because there is more friction.
Joel claims that “Bright White Toothpaste” removes tooth enamel stains better than all other brands. Which of the following should be documented as evidence to support his claim?

2. The shade of teeth before and after brushing

4. The size of tooth
Answers
The independent variable in this instance is the bright white toothpaste, and if they’re claiming that it removes stains better than all, then that means that the dependent variable would be the shade of teeth!
The amount of toothpaste, the type of tooth brush, and the size of tooth are all variables of the experiment but will not determine if the claim is supported or not.
