Think about a lake. Would you describe it as a homogeneous mixture, a heterogeneous mixture, or both? Explain
Answer:
homogenous mixture.
Explanation:
comprises of two or more substance which cannot be distinguished from one another. it forms a uniform mixture.
In chemistry, a mixture is a substance that consists of a combination of substances. It can be homogeneous or heterogeneous. The water of the lake is a homogeneous mixture.
What is a homogeneous mixture?Homogeneous mixture and heterogeneous mixture differ in the process of separation. The homogeneous mixture is defined by its uniform and definite composition.
They are not able to be differentiated and distinguish the components of the mixture. The substance appears to look like a single substance as no composition appears separately.
Lakes are considered homogeneous mixtures as the various components of the mixture are not able to be distinguishable. They appear as one and act as a single property.
Therefore, the lake is a homogeneous mixture.

Answer:
Answer:Monohybrid Cross
Answer:Monohybrid CrossIn a monohybrid cross, the parent organisms differ in a single characteristic. Suppose, for example, two humans have children. The father has a widow's peak and the mother does not. A widow's peak is a dominant trait, meaning that if the child inherits the gene for this trait from one parent, that child will have a widow's peak regardless of the gene inherited from the other parent.
Answer:Monohybrid CrossIn a monohybrid cross, the parent organisms differ in a single characteristic. Suppose, for example, two humans have children. The father has a widow's peak and the mother does not. A widow's peak is a dominant trait, meaning that if the child inherits the gene for this trait from one parent, that child will have a widow's peak regardless of the gene inherited from the other parent.Consequently, there are two possibilities. The child could inherit the widow's peak gene from his father, or he could inherit the non-widow's peak gene from his father. He will inherit a non-widow's peak gene from its mother, who does not have the widow's peak gene. In this particular monohybrid cross, there is a fifty-fifty chance that any given child will have a widow's peak.

Answer:Monohybrid CrossIn a monohybrid cross, the parent organisms differ in a single characteristic. Suppose, for example, two humans have children. The father has a widow's peak and the mother does not.

In this particular monohybrid cross, there is a fifty-fifty chance that any given child will have a widow's peak.Dihybrid CrossIn a dihybrid cross, the parents differ in two characteristics you want to study. The pattern of inheritance here is somewhat more complicated. Suppose, for example, that you have two parents, one of whom has dimples and a widow's peak while the other has no dimples and no widow's peak. Dimples, like a widow's peak, are a dominant trait. Consequently, if these two traits are not linked, each child has a 1/4 probability of inheriting dimples and widow's peak, a 1/4 probability of inheriting dimples but no widow's peak, a 1/4 probability of inheriting a widow's peak but no dimples, and a 1/4 probability of inheriting neither. Keep in mind, however, that linked traits might exhibit very different patterns.

What is the chemical formula for chlorophyll d?
The chemical formula for chlorophyll "d" is C54H70MgO6N4. This means that a single molecule of this substance contains 54 atoms of carbon, 70 atoms of hydrogen, 6 atoms of oxygen, and 4 atoms of nitrogen. And, also, that "Mg" symbol in the middle of the chemical formula stands for "Magnesium." Since it is in the middle for this chemical formula, this means that it is known as the central magnesium atom. I hope that this has helped find the answer that you were looking for. Enjoy your day, and take care.
The formula is C54H70MgO6N4. Hope this helps :)

the levels of biological organization. Put each element of bat vision in order from least to most
complex.
Start by clicking the first item in the sequence or dragging it here
Drag the items below into the box above in the correct order, starting with the first item in the sequence.
The retina of bats is made up primarily of rod cells, allowing bats to see well in dim light.
The optic nerve conveys the sensory information from the bat's eye to the visual cortex of the
brain.
Nitrogen is a necessary atomic element in proteins like visual pigments.
The musculoskeletal system of the bat acts on the information supplied by the nervous system
to capture prey.
The bat eyeball has adaptations to the retina and lens for low-light vision.
Rod cells have a high level of rhodopsin molecules, allowing visual acuity in low light.
Rhodopsin is a photopigment molecule that is highly sensitive to light.
Help me please
The levels of biological organization are atomic, molecular, cellular, tissue, organ and systems of organs (such as nervous and muscular systems).
The correct levels of biological organization from the simplest to the most complex are:Nitrogen is a necessary atomic element in proteins like visual pigments;Rhodopsin is a photopigment molecule that is highly sensitive to light;Rod cells have a high level of rhodopsin molecules, allowing visual acuity in low light;The retina of bats is made up primarily of rod cells, allowing bats to see well in dim light;The bat eyeball has adaptations to the retina and lens for low-light vision;The optic nerve conveys the sensory information from the bat's eye to the visual cortex of the brain;The musculoskeletal system of the bat acts on the information supplied by the nervous system to capture prey.The nitrogen (N) atom is a fundamental component of biomolecules such as DNA (nitrogenous bases) and proteins (aminoacids).Rhodopsin is a light-sensitive protein pigment that is abundant in the rod cells found in the retina. This pigment (rhodopsin) is responsible for night vision.There are two types of photoreceptor cells located in the retina: rod cells and cone cells. Rod cells are required for vision at low light levels.The retina and lens are parts of the eye: the retina is a layer at the back of the eye; whereas the lens is located behind the iris and the pupil. The visual system is composed of the eye (i.e., the sensory organ) and different areas of the central nervous system which include the optic nerve, optic tract, and visual cortex.The musculoskeletal system and nervous system work together in response to stimuli such as visual motion or stimulus localization.Learn more in:
