What are air plants?
Why don’t they need soil to grow?
How can this science help us cobalt real life problems ?

Answers

Answer:

1. Air plants are part of the Bromeliad family, air plants are epiphytes — plants that attach themselves to other plants for support, without relying on the host to thrive.

2. They absorb moisture and nutrients through their leaves, not their roots, which they use only to anchor themselves to other plants or objects. Since air plants don't absorb their nutrients through their roots, they can't be planted in the soil.

3. The internal structure and anatomy of Tillandsia have adapted to survive on varied hosts both alive and not. Their leaves are able to pull moisture from the air more efficiently while some have developed a camel-like ability to store water and survive in areas prone to drought. Being up in trees or on rocky cliffs protects these plants from damage done by foraging animals, flooding or erosion on the ground.

Explanation:

Epiphytic plants can be used to determine the elemental composition of the air and soil in which they grow, cycle nitrogen, affect water retention within the rainforest, and house many resources for various plants and animals.

Through the analysis of epiphytes, biologists can determine changes in air and soil composition over time. Air pollution in the rainforest can be monitored by the use of air plants.  By monitoring how mosses and lichens respond to different air pollutants, especially heavy metals, the effect that the toxins have on the environment can be determined In the rainforest, epiphytes can be placed in areas where there is ecological damage to determine if nearby pollutants are affecting the health of the forest and additionally play a role in nitrogen cycling.

Organisms are created by different types of tissues. These are composed of cells. Animals are made of animal cells which are round, and plants are made of plant cells which are rectangular and have cell walls.

Which of the following groups is difficult to define into species using the Biological Species concept?
A. Vertebrates
B. Asexually reproducing organisms
C. Sexually reproducing organisms
D. Insects

Answers

Asexually reproducing organisms groups are difficult to define into species using the Biological Species Concept.

Why is it difficult to define a species using the concept of a species?

In summary, the main limitation of the concept of organisms is that they are independent of ectopic speciation and are not applicable to (1) Fossil species. (2) Organisms with asexual reproduction or extensive self-fertilization. (3) Sexual organisms with an open mating system (seed that mates freely).

Asexual reproduction is a type of reproduction that occurs without cell or germ cell interaction. In the case of asexual reproduction, the organism does not need a spouse to reproduce. Organisms that undergo asexual reproduction to produce offspring are called asexual species.

What statement is true about cell walls.
1
Cell walls are present in animal cells
O All cells have cell walls
O Cell walls support, shape, and protection the cell
O In plants, cell walls are made of proteins

Answers

Answer:

Although 3 and 4 are great answers, I honestly think the answer is C. Because you can simply define the cell wall as a semi-rigid thick protective structure that surrounds the cell membrane of some types of cells for protection and defining the shape of the cell. The cell membrane alone cannot provide the required rigidity or strength. All living organisms are composed of cells. Cell walls contain only little amount of protein in the cell wall.

Explanation:

Not all cells have a cell wall; the cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell. Cell walls are found in both prokaryotes and eukaryotes, although not all cells have cell walls. Animal cells does not have a cell wall; Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not. Chloroplasts enable plants to perform photosynthesis to make food.

Explanation:

Michelle was curious about her mother's blood type. Michelle knew that her own blood type was o,
her father's blood type was A, and her two sisters and one brother both also had type A blood. How
could Michelle have type o when everyone else around her seems to have type A blood? Michelle is
really frustrated. Please help her out by making a possible Punnett square showing how this could
happen.

Answers

Blood type is determined by the I gene. IAIA and IAi determines A blood type. IBIB and IBi determines B blood type. ii determines 0 blood type. Michelle's mother must at least carry one recessive allele i.

--------------------------------

The blood type is determined by a gene, which is triallelic.

IA dominant over i. The person presents A type of antigens.

IB dominant over i. The person presents B type of antigens.

IA and IB are codominant. The person presents both types of antigens, A and B.

i is the recessive allele. The person does not present any antigen.

⇒  H0m0zyg0us dominant individuals IAIA, or heter0zyg0us Individuals IAi, will express the A blood type.

⇒  H0m0zyg0us dominant individuals IBIB, or heter0zyg0us Individuals IBi, will express the B blood type.

⇒ Individuals with h0m0zyg0us recessive genotype, ii will express the 0 blood type.

⇒ Individuals carrying IA and IB alleles will express the AB blood type.

To solve the problem, we will use this information.

We know that

Michelle is blood type 0

Father is blood type A

Brother and sister are blood type A

Mother??

⇒ If Michelle is blood type 0, then her genotype is ii. She must have received one recessive allele from her father and one from her mother.

⇒ This suggests that Michelle's father, who is blood type A, is heter0zyg0us IAi. He must have at least one dominant allele IA that determines his phenotype, and one i allele.

⇒ Michelle's brother and sisters are also type A. They might be either h0m0zyg0us dominant IAIA or heter0zyg0us IAi.

⇒ Michelle's mother should have at least one recessive allele i. She could be either IAi or IBi, or ii. There are three possible option for her genotype.

Let us make the Punnet squares to understand it better. We know the genotype of the father, but there are three options for the mother.

Option 1

Cross)   father x mother

Parentals)  IAi     x     IAi

Gametes)  IA    i      IA     i

Punnett square)      IA       i

                       IA    IAIA    IAi

                        i     IAi       ii

F1) 25% of the progeny is expected to be h0m0zyg0us dominant IAIA

     50% of the progeny is expected to be heter0zygus IAi

     25% of the progeny is expected to be h0m0zyg0us recessive ii

75% of the progeny is expected to be blood type A ⇒ IAIA and IAi ⇒ Sisters and brother

25% of the progeny is expected to be blood tye 0 ⇒ ii ⇒ Michelle

Option 2

Cross)   father x mother

Parentals)  IAi     x     IBi

Gametes)  IA    i      IB     i

Punnett square)      IA       i

                       IB    IBIA    IBi

                        i     IAi       ii

F1)  25% of the progeny is expected to be IAIB

     25% of the progeny is expected to be heter0zygus IAi

     25% of the progeny is expected to be heter0zygus IBi

     25% of the progeny is expected to be h0m0zyg0us recessive ii

25% of the progeny is expected to be blood type AB ⇒ IAIB

25% of the progeny is expected to be blood type A ⇒ IAi ⇒ Sisters and brother

25% of the progeny is expected to be blood type B ⇒ IBi

25% of the progeny is expected to be blood tye 0 ⇒ ii ⇒ Michelle

Option 3

Cross)   father x mother

Parentals)  IAi     x     ii

Gametes)  IA    i      i     i

Punnett square)      IA       i

                        i     IAi        ii

                        i     IAi        ii

F1)  50% of the progeny is expected to be heter0zygus IAi

     25% of the progeny is expected to be h0m0zyg0us recessive ii

50% of the progeny is expected to be blood type A ⇒  IAi ⇒ Sisters and brother

50% of the progeny is expected to be blood tye 0 ⇒ ii ⇒ Michelle

Despite the fact we can not determine for sure the mother's genotype, we know that she carries at least one recessive allele, which is why Michelle's blood type is 0.

The system that maintains the human species from generation to generation is the REPRODUCTIVE system. This system is responsible for producing male and female gametes.

The reproductive system is an organ system by which humans produce male (sperm) and female (ovule) gametic cells.

Male and female gametes fuse during fertilization to produce a diploid zygote that develops into an adult individual.

In women, the reproductive system is composed of the ovaries, uterus, fallopian tubes, cervix, and vagina.

In men, the reproductive system includes the testes, prostate, and penis.

5. Juan’s cell phone company charges $35 a month for the phone service plus $0.50 for each text message. How many text messages does Juan send in a month if his bill was $52?

Answers

Answer:

34

Explanation:

Total Cost = Fixed Charge + 0.50 * number of text messages

Total Cost = 52 dollars.

text Messages = x

Fixed charge = 35 dollars.

Equation

Total Cost = Fixed Charge + number of text message * 0.50

Solution

52 = 35 + 0.50 * x                  Subtract 35 from both sides

52 - 35 = 35-35 + 0.50x        Combine

17 = 0.50x                               Divide by 0.50

17/0,50 = 0.50*x/0.50
