Bob has brown hair and Sally has blonde hair. If brown hair is dominant and blonde hair is recessive, is it possible for Bob and Sally to have a blonde-haired child? Use the GENOTYPE of each parent to EXPLAIN your answer.

Answers

Answer 1

Answer:

Yes, it is possible.

Explanation:

Bob could either be h.o.m.ozygous (BB) for brown hair or h.e.terozygous (Bb) for brown hair. If Bob is h.e.t.erozygous for brown hair, this means he has a blonde hair allele. For a child to be blonde, the child needs one blonde allele from each parent and this is possible if Bob has a blonde hair allele. However, it is not possible if Bob is h.o.m.ozygous for brown hair.

In the image, there is a punnet square showing the possible genotypes of the children if Bob is h.e.t.erozygous for brown hair.

A disease-causing bacteria successfully enters your body, making it past the first and second lines of defense. Which barrier will then act on the bacteria? chemical physical biological electrical.

Answers

Answer:

The correct answer is biological.

Explanation:

When any pathogen invades the body, it has to pass several lines of defence. The first barrier is the skin and mucous membrane which is a physical and chemical barrier. The second line of defence is the non-specific response by macrophages, neutrophils and interferon. After crossing these two barriers the third line of defence comes into action in which, the B- cells and T-cells act specifically on the pathogen and destroy it.

Answer:

[tex]\huge\boxed{\sf Biological}[/tex]

Explanation:

When first and second line of defense is passed by the bacteria, the third line of defense will come into action which is a biological barrier which includes antigen which are anti-bodies generating substances.

C.

Environmental factors influence traits in plants and animals. These traits include things like weight, height, size, and color. If a dog does not get proper nutrition and exercise, their weight will be negatively impacted. The dog is likely to be overweight if the environmental factors are not changed.

For this discussion, explain how each organelle in a eukaryotic animal cell is interconnected with the others. You will need to write at minimum a couple of paragraphs but at most as much as it will require for you to answer this.

Answers

Answer:

Different organelles make close contacts with each other via MCSs. These contact sites are generally thought to form via membrane proteins that act as tethers on the interacting organelles . Often these tethers are part of large multiprotein complexes.

The endomembrane system (endo = within) is a group of membranes and organelles in eukaryotic cells that work together to modify, package, and transport lipids and proteins. It includes the nuclear envelope, lysosomes, vesicles, endoplasmic reticulum and the Golgi apparatus, which we will cover shortly.

There are two types of proteins: structural proteins and enzymes. Cell organelles must work together to carry out protein synthesis, utilize proteins within the cell, and transport them out of the cell.

this year there were 32 ants born in an ant hive. Due to the new pesticide that was used in the area, 32 died. With an overall population of 1000 ants in the hive, what is the change in population? Do you have a positive, negative, or zero change in population? How many members are in the new population?

Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. Work for calculating the new population.

Answers

Answer:

0 change in population. I think.

Explanation:

first we are adding 32 ants to the total because 32 ants were born so 1000+32 = 1032.

Next we are subtracting 32 ants from the new total because a pesticinde was used in the area. So 1032 - 32 is 1000. 1000 was the original total so there was not a decrease in popualtion or an increase.

Answer :

Incubation is 18 days from the time cockatiels sit in earnest, therefore, count a few extra days if sitting is delayed. Allow the female to abandon the eggs of her own accord rather than removing them even if incubation time is over, because your cockatiel will only lay additional eggs if she reacts to their absence.

Answers

Answer:

1. 50%

2. Every gamete only contains 50% of the genetic information or half of the information for a gene.

Explanation: 1. Heterozygous means the pairs consist of a dominant and a recessive, or one big and one small letter, so only 2/4 or 50% are heterozygous.

2. Every sex cell has half of the chromosomes you need to make an embryo so you end up only having one allele as well

Heterogeneous means different

Essential Question: What is the relationship between photosynthesis
and respiration?

*Zoom in to the picture for a better view

Answers

Answer:

I. Examine Details

1. In what cell organelle does photosynthesis occur? cellular respiration?

Photosynthesis occurs in the chloroplast, while cellular respiration occurs in the mitochondria.

2. What are the three things needed for photosynthesis? Highlight them on the diagram in  green.

Sunlight, carbon dioxide, and water

3. What are the two products of photosynthesis? Highlight yellow.

Glucose and oxygen

4. What are the two things needed for cellular respiration? Highlight blue.

Glucose and oxygen

5. What are the three products of cellular respiration? Highlight purple.

Carbon dioxide, water, and ATP

6. What things are recycled (used over and over again) during photosynthesis and  respiration?

Carbon dioxide, water, oxygen and glucose

II. Apply (what you already know)

7. Sketch a model of typical plant cell and identify the mitochondria and chloroplasts.

8. What will happen to plants that are kept in the dark?

Plants will die since plants need daylight to deliver food. If there is no admittance to  sunlight, the Light Dependent response will not happen.

9. What will happen if you forget to water your plants?

The plants will die since water is a necessary reactant photosynthesis.

10. What happens to animals that are deprived of oxygen?

Those animals will not be able to perform cellular respiration.

III. Big Ideas

11. One hypothesis regarding the extinction of dinosaurs is that a meteor hit the earth  causing an explosion so powerful that dust blocked out the sun. Consider the model  above and explain why would this have caused a mass extinction?

Obstructing the Sun would cause the powerlessness for essential makers, for example,  plants, to go through photosynthesis, in this way not creating its own food fundamental for  development and energy.

12. When you walk your dog, you are using energy from the sunlight to power this activity.  

Explain. Sunlight gives the energy to essential makers to make their own food, using the carbon  dioxide and delivering oxygen gas as a result of photosynthesis. The oxygen that is  delivered into the environment is taken in by life forms as a reactant in respiration. Oxygen  allows for ATP creation. The ATP is the substance energy structure that is needed to convey all cell processes such as walking your dog.

13. Carefully and completely answer the "essential question" of this activity. Use complete  sentences and details from the model to explain your position.

Essential Question: What is the relationship between photosynthesis and respiration?

Photosynthesis and respiration are related since the reactants of photosynthesis are the  products of cellular respiration, and vice versa. For example, the reactants of  photosynthesis are energy, carbon dioxide, and water, while the products are oxygen and  glucose. The reactants of cellular respiration are oxygen and glucose, while the products  are energy, carbon dioxide, and water.
