Answer:
A
Explanation:
The genotypic mix of the two genes, or alleles, that make up an expressed trait is what causes it. Additionally, a specific gene produces a distinct protein that establishes an individual's physical traits. This is how traits are controlled by genes. Thus, option A is correct.
What is the effect of genetic rules in the Gizmo?The genotype, or set of genes an organism acquired from its parents, is ultimately responsible for the qualities that creature manifests. Each chromosome in an animal has two copies, one from each parent.
Cloning and fingerprinting are two potential applications for DNA-based identification technology.
Device Warm-Up DNA profiling compares more than just one person's full genome to another. Instead, only one specific section of the DNA is compared.
Therefore, parent 1 plant is wrong in the picture.

What is carbon cycle?Carbon cycles through Earth's atmosphere, oceans, land, and living things. Carbon is essential to numerous life-sustaining chemical processes. Carbon dioxide (CO2), which plants use for photosynthesis and regulates Earth's temperature, is in the atmosphere.
Several Earth processes transport carbon between reservoirs in the carbon cycle. Photosynthesis, respiration, and decomposition. Plants employ photosynthesis to convert CO2 into organic carbon molecules like sugars for growth. Plants and animals respire to release CO2 into the atmosphere. Decomposition by microorganisms releases CO2 from dead plants and animals.
The carbon cycle is a crucial aspect of Earth's climate system, regulated by CO2 levels, photosynthesis and respiration rates, and greenhouse gas levels. Understanding the carbon cycle helps us comprehend climate change and identify solutions.

It is theorized that the continents on Earth were once joined together,
forming a supercontinent called Pangaea. How long ago did Pangaea
exist? How were the continents of Africa and South America arranged in
relation to each other? Describe one piece of evidence to support their
relationship. Write your response in complete sentences
Answer:
Pangea existed many millions of years ago in many opinions, but it started back in the late Paleozoic Era until the very late Triassic. Pangea first began to be torn apart when a three-pronged fissure grew between Africa, South America, and North America. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.
Explanation:
Answer:
Pangaea is believed to have existed around 335 million years ago during the late Paleozoic and early Mesozoic eras.
During this time, the continents of Africa and South America were joined together as part of the supercontinent Pangaea. They were located in the southern hemisphere, with Africa to the east and South America to the west.
One piece of evidence to support their relationship is the similarity of plant and animal fossils found on both continents. Fossils of the ancient reptile Mesosaurus have been found in both Africa and South America, indicating that the two land masses were once connected. The distribution of fossils of other plant and animal species also suggests that Africa and South America were once part of the same landmass.
The theory of Pangaea and continental drift was first proposed by Alfred Wegener in the early 20th century, and it has since been supported by a range of geological and paleontological evidence. The movement of the continents has had a profound impact on the evolution of life on Earth, as it has created new habitats and allowed for the evolution of new species in isolation.
Is it likely that scientists will unearth something that will show the theory of evolution to be false?
Answer: Yes
Explanation: As time passes Scientists discover new things every day. The chance of them finding something to prove the theory of evolution is highly possible. Hope this helps.

The theory of evolution has changed over time. Initially, Lamarck believed that organisms developed traits in response to a changing environment to improve their chances of survival. Later Darwin proposed that organisms that already possessed traits suitable to a changing environment were more likely to survive and reproduce.
Which of the following does not explain why the theory of evolution has changed?
A. Lamarck’s theory was discarded when new scientific information became available.
B. Darwin collected empirical evidence to support that organisms with favorable traits survived and reproduced.
C. The theory of evolution became a scientific law after much debate and confirmation in the scientific community.
D. Other scientists such as Peter and Rosemary Grant have collected additional empirical evidence that supports Darwin’s findings.
What are some examples of suitable environments for bacteria?
How might bacteria avoid dying if an environment is not suitable?
How are bacterial cells different from plant and animal cells?
Describe how bacteria reproduce. How can bacteria acquire new characteristics?
Answer:
bacteria are found everywhere even in hot springs. Bacteria are different from other organisms because they don't have membranes bound organelles .they replicates to produce
Explanation:
Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.
How might bacteria avoid dying if an environment is not suitable?Many types of bacteria, if environmental conditions become unfavourable (lack of water, increase in temperature, etc), will go into a sort of dormant state, called an Endospore.
How are bacterial cells different from plant and animal cells?Because bacteria are prokaryotic, they do not have a nucleus and no membrane-bound organelles. In contrast, plants and animals are made up of eukaryotic cells, which means they have a nucleus and membrane-bound organelles like mitochondria or Golgi apparatus.
Describe how bacteria reproduce. How can bacteria acquire new characteristics?Bacteria reproduce through a process called binary fission. During binary fission, the chromosome copies itself, forming two genetically identical copies. Then, the cell enlarges and divides into two new daughter cells. The two daughter cells are identical to the parent cell.

Answer: 50%
Explanation:
I got 50% because the purple and white is a 50/50 chance. Meaning that the white is 50% and the purple would be a 50%.
The large P is Horizontal and all the small p are on the top. The large P is dominant, while small p is not. If there were 2 big P then all flower crosses would be purple.

Look at the diagram of the rock cycle below.
Which part of the cycle is missing?
A.
sedimentation
B.
melting
C.
crystallization
D.
mineral integration
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.
