Answer:
Option D
Explanation:
The complete question is
A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
a) Energy was destroyed during certain steps in the experiment.
b) The steps in the experiment required more energy than was available
c) The experiments created energy that was then used up at a faster rate.
d) Some energy was transformed into unwanted heat or sound that was not detected
Solution -
Option D is correct
While transfer of energy through any medium, some energy is lost in the form of heat and light. This loss of energy is not accounted at the beginning of the process and hence the initial energy loss was zero. With the succession of the process energy kept loosing and hence the final energy count was low at all steps.

In the scenario above, Red hair (R) is dominant to blonde hair (r). If two parents are
heterozygous for red hair, what percentage of their offspring will have red hair and what
percentage will have blonde?
Answer:
75% of the offspring will have red hair and 25% will have blonde hair.
Explanation:
Since red is dominent but heterozygous it will be represented like Rr. Since both parents have that put it on a punnet square to get 75% red and 25% white.

how does natural selection affect different variation of the same species?
Answer:
Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.
Explanation:
Through this process of natural selection, favorable traits are transmitted through generations. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.
Describe how some cells make food molecules
Answer:
All living cells release energy from food molecules through cellular respiration and/or fermentation. Some cells make food molecules using light energy through the process of photosynthesis
Explanation:
basiclly light and some cells eat others
Answer:
Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Explanation:
In which way is cellular respiration similar to photosynthesis?
a. they both make G3P
b. the both involve ATP
c. the they both involve chemiosmosis
d. all of the above
Answer:
if I am correct it would be b
Explanation:
Starch and glycogen are types of this macromolecule.

In 2019, Iceland recorded 7890 births and 123 deaths per week. What was the Population Growth Rate for Iceland?
Answer:
The Population Growth Rate was 403884 in 2019
Explanation:
Lets first calculate how many total new lives per week iceland had.
Births - Deaths = New Lives
7890 - 123
=
7767
So we have 7767 lives that are new every week.
So like a 7767 growth.
But I think the growth rate is yearly.
So with 52 weeks in a year lets multiply the amount of weeks with the new lives weekly.
7767 x 52
=
403884
The Population Growth Rate was 403884 in 2019.
I hope this helps.

organisms are classified as either prokaryotes and eukaryotes.which of the following do the cells of all prokaryotes and eukaryotes contain?
Answer:
Prokaryotes contains a single chromosome and DNA whereas eukaryotes contain true nucleus and organelles.
Explanation:
The cells of all prokaryotes contains a single chromosome and a double-stranded DNA while on the other hand, nucleus and other organelles are absent whereas eukaryotes contain true nucleus and organelles such as golgi bodies, endoplasmic reticulum, lysosomes, ribosomes, vacuole and mitochondria. True nucleus means the membrane is present around the nucleus.
Answer: A plasma membrane and cytoplasm

What are the levels of organization in the human body, starting with the cell?
Answer:
cells
v
tissues
v
organs
v
organ system
v
organism
cells make tissues that build up organs to build a organ system then organism (you,a human)
cells are the building block for life
The level of organization in the human body initiates with the cell and process in the manner which is as follows:
Cell < Tissue < Organ < Organ system < Organism. What is the level of organization?The level of organization may be defined as the process of sequence from the structures that are simplest in nature. It is usually defined by part-whole relationships, with things at higher levels being composed of things at the next lower level.
In organisms, a cell is the fundamental structural and functional unit of life. The collection of cells constitutes the formation of tissue which makes an organ that plays a specific function. Groups of organs form organ systems. While all cells, tissues, organs, and organ systems combine in order to form multicellular organisms.
Therefore, the level of organization in the human body initiates with the cell and processes in the manner which is well-described above.

Explanation:
rate of reproduction to sexual reproduction in plants
Answer: Asexual reproduction
For example, sexual reproduction allows for variation, but gestation usually takes a long time and it requires heavy parental input. Asexual reproduction occurs quickly, but because all of the offspring have the same genetic information, individuals are more susceptible to disease.
