Which organisms undergo Carnegie stages? A lizard B sheep C snail D worm YOU CAN CHOOSE MORE THAN ONE ANSWER!
Answer:
Sheep
Explanation:
Carnegie stages can be described as the period of maturation in mammals. It is during this period that they develop most of the body parts and organs that is needed for them to survive in the outside world. There are about 23 stages which classify the ways each mammals form and develop various features on their bodies.
The Carnegie Stages of development are unique to mammals this is because mammals carry their young one in their wombs, they stay there deriving nutrient from their mother until they are ready to be born. From the options listed above the mammal among the animals, there is sheep. Hence a sheep undergo Carnegie stage.

Which statement describes how heterotrophs depend on autotrophs for survival?
A) Autotrophs supply oxygen for respiration.
B) Autotrophs provide sunlight for respiration.
C) Autotrophs make lactic acid for respiration
D) Autotrophs produce carbon dioxide for respiration
Answer:
A
Explanation:
i took a test got it wrong but it showed me this is the answer :)
The organism that is incapable of producing food for their needs and depends on other organisms are called heterotrophs while the food-producing organisms are called autotrophs.
Autotrophs supply oxygen for respiration to the heterotrophs.
The dependency of heterotrophs can be explained as:The autotrophs are capable of producing oxygen from the sunlight, carbon dioxide and water by the process of photosynthesis. The heterotrophs are incapable of utilizing the atmospheric carbon dioxide and the water to yield oxygen needed for respiration.Therefore, option A. the autotrophs provide oxygen to the heterotrophs for respiration.

In human genetics, the allele for having freckles is inherited apart from the allele for having attached earlobes. Which one of Mendel's principles does this illustrate?
A- Principle of Alleles
B- Principle of Dominance
C- Principle of Independent Assortment
D- Principle of Segregation
Explanation:
The answer is B., because if freckles are a dominate trait between a female with freckles and a male with freckles, they're offspring will have a dominant trait of freckles..
Mendel's principle that describes this condition is known as the Principle of Independent Assortment. Thus, the correct option for this question is C.
What is the Principle of Independent Assortment?The Principle of Independent Assortment states that the two factors of each character separate out independently of the factors of the other characters at the time of gamete formation.
They get randomly rearranged in the offspring producing both parental and new combinations of new characters. According to the question, freckles are dominant over no freckles and unattached earlobes are dominant over attached earlobes.
This states that the factors of each character separate out independently. That is why the genes of these characters are not linked or associated with each other.
Therefore, the correct option for this question is C.

Which part of your integumentary system is found on the outside of your body? *
a. Epidermis
b. Keratin
c. Dermis
d. Melanin
Answer:
The correct answer is a. Epidermis.
Explanation:
The skin is made up of two layers that have different structure and origin: epidermis and dermis, which are closely related. The epidermis is the most superficial part of the skin and is made up of a keratinized flat stratified epithelial tissue, where several layers or strata can be seen that, depending on their greater or lesser development, allow the skin to be classified into thick and thin. The thick skin is on the palms of the hands and the soles of the feet and is characterized by a thick layer of keratin and by having a so-called lucid layer that does not exist in thin skin. Thin skin also has keratin, but the thickness of the keratin layer is much less. The epidermis is separated from the dermis by a limiting membrane, the basement membrane, which measures 50-70mm thick and is attached to the dermis by reticular fibrils that show axial periodicity.

Describe what happens as a plant's turgor pressure increases and decrease AS MUCH POINTS AS I CAN GIVE
Answer:
Brainliest pls
Explanation:
Turgor pressure in plants. Turgor pressure within cells is regulated by osmosis and this also causes the cell wall to expand during growth. Along with size, rigidity of the cell is also caused by turgor pressure; a lower pressure results in a wilted cell or plant structure (i.e. leaf, stalk).
Turgor pressure in plants plays a key role in processes such as growth, development, mechanical support, signalling, flowering and stress response. Turgor pressure is an ideal means in plant cells through which the energy content of water molecules (water potential) can be adjusted quickly, within seconds.

You run one lap around the track at a constant 11 km/h. What changes?
Answer:
Your velocity
Explanation:
This is because the direction is changing. The speed doesn't change since it's constant
When we run one lap around the track at a constant 11km/ hr., the velocity will change as we are changing the direction, speed will remain constant.
What is Velocity?Velocity is defined as the directional speed of a moving object that indicates the rate of change of position as observed from a particular frame of reference and as measured by a particular standard of time.
Velocity is the vector quantity as it has both magnitude as well as direction. Speed is the rate of change of distance while the velocity is the rate of change of displacement. It can be measured by the formula which is :
[tex]\overline{v}={\frac{\Delta x}{\Delta t}}\\\overline{v} = average velocity\\{\Delta x} = displacement\\{\Delta t} = change in time[/tex]
It's SI unit is m/s.
In the given information, the track is in circular form due to which the direction is changing resulting in change in velocity as it is the rate of change of displacement.
Thus, when we run one lap around the track at a constant 11km/ hr., the velocity will change as we are changing the direction, speed will remain constant.

What is the function of the Single Strand Binding Proteins (SSB. during DNA replication?
O to add new nucleotides to each strand of DNA
O to seal up the new nucleotides (Okasaki fragments) into long continuous strands
O to bind temporarily to each strand of DNA and keep them separated during replication
O to break the hydrogen bonds holding the two DNA strands together
Answer:
the correct answer is C.
Explanation:
Once helicase separates the strands by breaking the bonds between them, there's still some sort of attraction between the two strands. This is were the SSB's come in. They help to keep the strands apart, preventing them from coming back together.
The single-stranded DNA binding protein (SSB) wraps (ssDNA) during DNA replication with a strong affinity to shield it from deterioration and prevent the development of secondary structures. Option (C) is correct.
What is DNA Replication?The formation of two identical copies of a double-stranded DNA molecule requires a process known as DNA replication. This process copies the DNA molecule so that it has both strands.
The requirement for replication results from the fact that whenever a cell divides, the two daughter cells must have the same genetic material, also known as DNA, as the parent cell. This makes it necessary for replication to take place.
The cytoplasm of prokaryotic cells and the nuclei of eukaryotic cells are the locations where DNA replication takes place. The basic processes involved in DNA replication are consistent regardless of where it is carried out. The development of the primary nucleoprotein complex substrate is essential for the processes of DNA replication, recombination, and repair. SSBs contribute to its formation.
Therefore, option (C) is the correct answer.

Answer:
Due to fast transportation of oxygen, waste material and nutrients.
Explanation:
Gills, a heart, and a closed circulatory system are more efficient ways to provide oxygen to all cells than that of open circulatory system of insects because in the closed circulatory system blood transfers is faster than open circulatory system, thus oxygen, nutrients, and wastes transport is also very fast so we can say that closed circulatory system is more efficient than open circulatory system.
