why is energy not conserved in the carbon cycle
Answers
Energy is not conserved in the carbon cycle because it is an open system.
Why is energy not conserved in the carbon cycle?Energy is not conserved in the carbon cycle, but it is transformed from one form to another. For example, the energy stored in carbon compounds such as glucose is released through cellular respiration and used by organisms for growth and metabolic processes.
The carbon cycle also involves the transfer of energy from the sun to plants through photosynthesis, and from the atmosphere to the ocean through the dissolution of carbon dioxide. Overall, energy is neither created nor destroyed in the carbon cycle, but is transformed from one form to another.

In E. coli bacteria, the lac operon contains genes that code for enzymes that break down lactose. Which statement describes when the genes in the lac operon are expressed?
Answers
The genes in the lac operon are expressed when lactose is present and the repressor protein is unable to bind to the operator region.
In E. coli bacteria, the lac operon contains genes that code for enzymes involved in lactose metabolism. The lac operon is a regulatory system that controls the expression of these genes. The expression of the genes in the lac operon is tightly regulated and depends on the presence or absence of lactose and glucose in the environment.When lactose is present, it binds to the repressor protein (lac repressor), causing a conformational change in the repressor. This change prevents the repressor from binding to the operator region of the operon. As a result, RNA polymerase can bind to the promoter region and transcribe the genes, leading to the production of the enzymes that break down lactose.In the absence of lactose, the repressor protein binds to the operator region and blocks RNA polymerase from initiating transcription. This prevents the expression of the genes in the lac operon.For more questions on protein

ii. All existing cells are produced by other living cells.
iii. The cell is the most basic unit of life.
7. Cell theory is one of the great unifying theories of biology
Explanation:
Cell theory is one of the central theories of biology and is universally accepted. It states that all organisms are cellular - that is they are made of cells. It also states that all living things come from other living cells (not spontaneously, or from dead cells). The cell is the most basic unit of life, organisms can be unicellular, but no living thing is 'less' than that.
Most articles pass right through the atom, this means that most of the atom is
Answers
Most articles pass right through the atom, this means that most of the atom is an empty space.
What is an atom?An atom is described as a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.
Protons and neutrons make up the core nucleus of an atom, which is encircled by an electron cloud. In relation to the size of the atom as a whole, the nucleus is exceedingly small.
As a result, the electrons surrounding the nucleus are the primary target of interactions when particles or even light pass through an atom. The majority of the atom's remaining space, which includes the nucleus, is vacant.

b) Porifera − gastrovascular cavity, coelom
c) Echinodermata - radial symmetry as a larva, coelom
d) Platyhelminthes − flatworms, gastrovascular cavity, no body cavity
Answers
The phylum and description that is correct among the options is Platyhelminthes − flatworms, gastrovascular cavity, no body cavity
Flatworms belongs to the phylum platyhelminthes. They are said to have no true body cavity, but they do have bilateral symmetry. For the lack of a body cavity, it is called acoelomates. They also have an incomplete digestive system. That is, the digestive tract has only one openingsFrom the above we can therefore say that Option d is the correct option that gives the true description of the phylum platyhelminthes

Both plants and animals consume oxygen during photosynthesis.
Plants produce oxygen needed by animals for photosynthesis.
Animals produce oxygen needed by plants for respiration.
Answers
Answer:fter photosynthesis, plants release oxygen into the atmosphere. This is one of the most significant ways that plants contribute to the carbon cycle's oxygen cycling.
In the process of photosynthesis, plants create oxygen and glucose, a form of sugar, from carbon dioxide, water, and sunshine. Animals and other species use the waste product of photosynthesis, oxygen, which is discharged into the atmosphere, for breathing. Overall, photosynthesis and plant respiration are just two examples of the numerous creatures and natural processes that contribute to the intricate process of oxygen cycling in the carbon cycle.
Therefore, the correct option is B.

Which factors changed throughout the experiment? Check all that apply
Answers
In the experiment, two factors changed throughout the course of the study: the genes of the parental mice and the fur color of the offspring.
The genes of the parental mice: The experiment involved studying the genetic makeup of the parental mice, specifically focusing on the alleles responsible for fur color. The researchers likely examined the genes of the parental mice to determine which alleles they carried and how they could potentially be passed on to their offspring. By studying the genetic composition of the parental mice, the researchers could track the inheritance pattern of the fur color trait.
The fur color of the offspring: The primary objective of the experiment was to investigate how fur color is inherited in mice. To achieve this, the researchers likely observed and recorded the fur color of the offspring produced by the parental mice.
As the experiment progressed and new generations of mice were born, the researchers would have noticed changes in the fur color of the offspring. By comparing the fur color of the offspring to the known genetic makeup of the parental mice, they could analyze the inheritance patterns and determine whether specific alleles were dominant or recessive.

Which description best supports the skeletal findings? a. The skeletal remains most likely belong to a male over the age of 60. b. The skeletal remains most likely belong to a male under the age of 60. c. The skeletal remains most likely belong to a female over the age of 60. d. The skeletal remains most likely belong to a female under the age of 60.
Answers
The skeletal remains most likely belong to a female over the age of 60. Option C
How do we identify the skeletal remains?The skeletal remains most likely belong to a female over the age of 60.
A wide subpubic angle on the pelvis is a characteristic of female skeletons.
Completely fused coronal suture is an indication of middle age but could differ from person's to person.
A skull with a V-shaped mandible is also more common in females than males. The age of the individual can be estimated from the fusion of the coronal suture, which typically occurs between the ages of 30 and 40.
