In Labrador retrievers, the allele for black coat color (B) is dominant to the allele for brown coat color (b). However, if a lab has two copies of the recessive allele for a pigment-depositing gene (e), it can only have yellow coat color. In a cross of two doubly heterozygous black labs (BbEe x BbEe), what fraction of the next generation would one expect to be yellow

This is called an ion. :)

Answer:

the independent is the age of the tree and the dependent is the diameter

Explanation:

the diamter of the tree is based off of the age as we can see that it gets bigger the older the tree is

Answer: Independent variable: age of the tree (years), Dependent variable: tree diameter (mm)

The diameter of the tree is dependent on what age the tree is. As the tree gets older, the diameter increases. The dependent variable depends/relies on the value(s) of the independent variable.

Answer:

D. In mitochondria, during cellular respiration.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

All living organisms such as plants and animals require energy to function properly (life activities). Thus, the organelle where energy from nutrients is released is generally referred to as mitochondria. Animals retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

In organisms other than plants, the most ATP is produced in mitochondria, during cellular respiration.

What do you mean by arteries?

The arteries are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. Each artery is a muscular tube lined by smooth tissue and has three layers: The intima, the inner layer lined by a smooth tissue called endothelium.

What is oxygenated blood?

Oxygenated blood can be simply defined as a blood cell with large percentage of oxygen and low in carbon dioxide. It appears bright red in color and travels away from the heart to different parts of the body.

Answer:

Cytokinesis in eukaryotic animal cells do not have a cell wall, it occurs through a strangulation process carried out from the plasma membrane, this process is called segmentation. Plant cells are characterized by cytokinesis based on septate, since the cell wall does not allow strangulation.

Explanation:

Cytokinesis means: cell division, it is a cellular process parallel to mitosis whose purpose is the division of the stem cell's cytoplasm between daughter cells. In animal cells, cytokinesis occurs by cleavage. At the end of anaphase and during telophase, the central part of the cell narrows, forming the segmentation groove, which deepens (strangulation). Plant cells, as they lack centrosomes, will form the achromatic spindle from two polar caps. In this case, cytokinesis does not occur by strangulation, but a cell wall is formed between the two daughter cells. This septum, called a fragmoplast, is formed from vesicles from the Golgi apparatus.

The major difference during cytokinesis in eukaryotes with or without a cell

wall is in the formation of cell plate in cells with cell wall while in animal

cells cytokinesis occurs through the formation of a cleavage furrow.

Cytokinesis is the process of cell division in which the cytoplasm divides

into two. Plants have cell walls while animals lack cell walls.

Animal and plant cells form cleavage furrow and cell plate respectively

which aids division into two equal parts.

Mistletoe extracts water and nutrients from the spruce, to the spruce tree's detriment. The relationship that is shown here between the mistletoe and the tree is Parasitism. Hence, the correct option is B.

Parasitism refers to a type of symbiotic relationship in which one organism benefits at the expense of the other organism, which is called host. The parasite lives on or inside the host and derive nutrients as well as shelter from the host, thereby providing no benefit to the host in return.

Examples of parasites includes tapeworms, roundworms, lice, fleas, and some species of bacteria and viruses.

Parasitism is a common for of symbiosis in nature and play an important role in shaping the relationships between species and maintaining balance in ecosystem. Hence, the correct option is B.

Please find the explanation of independent and dependent variables below using the experiment in this question.

Explanation:

Independent variable is the variable that the experimenter changes or manipulates in an experiment while the dependent variable is the variable being measured in the experiment.

According to this question, a biology student who has grown tomato plants for several years wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer, which he used previously.

In this case, the "natural compost" is the independent variable while the dependent variable is how tall and fast the tomato plant will grow. Hence, the tallness or fastness is the dependent variable.

Answer:

Inherited traits are controlled by two factors that separate during reproduction.

Explanation:

Answer:

Contact inhibition

Answer:

The benefits of being able to regulate the internal body temperature are many and it is considered a beneficial evolutionary character, since in this way the living organism is better maintained in relation to the environment, and it achieves better balance.

Reptiles cannot control their internal temperature, it depends on the external one, that is why to warm their body they need to be in the sun, and to cool down in the shade or in temperate places.

This is a little evolutionary characteristic since the environment is very changeable and the right or ideal temperature for the organism could not be controlled.

Explanation:

Faced with climatic catastrophes or extreme situations, living organisms cannot depend on the great climatic variants, in very cold situations one enters hypothermia and in very hot conditions the proteins are systematically denatured, entering a thermal shock.

Agricultural technology has evolved over time, with significant leaps during the agricultural and green revolutions.

Agriculture has been one of the sustainers (along with hunting) of early men and as such, has seen gradual development with time. Man has always been looking for better ways to do things in order to achieve outcomes.

With the era of the agricultural revolution, there was a huge transition of humans from the primitive lifestyle of hunting and fruit gatherings to that of agricultural settlements. Better ways to carry out crop production started receiving huge attention. from there, hand-made agricultural equipment started surfacing.

The green revolution has agriculture receiving utmost attention in terms of technological innovations. Farm machinery, agrochemicals, etc, started coming up with the result being a massive increase in crop production and general outputs.
