Answer:
Elastin
Explanation:
The elastin is defined as an extracellular matrix protein which lends to the elasticity and also resilience to the tissues such as the lungs, skin, arteries, tendons, and the ligaments.
Elastin synthesized from precursor molecule named tropoelastin.
Elastin is the fibrous protein which gives the skin its flexibility and also helps the skin regain its shape.
Which wound usually involves ears, fingers, and hands, and results in tearing or pulling off of a flap of skin
Answer:
Avulsion.
Explanation:
Human bite wounds are blunt wounds, sometimes with partial or total avulsion (ear, lips, nose, hands) and with intense contamination. An avulsion is a complete tear of the skin and subcutaneous tissue. It does not allow the approximation of edges. It presents moderate to abundant hemorrhage and is accompanied by the exposure of underlying tissues (bone, tendon). The tear can be complete or partial; in the latter case, a connection or bridge is preserved between the torn tissue and the rest of the body.
The image shows a rain forest ecosystem. The energy from plants, or producers, acts as the starting point of energy in the ecosystem. This energy is transferred to other organisms in the food web. In which two ways is the total amount of energy conserved in the ecosystem?
Some energy is transferred to the organisms, and the remaining energy is released into the ecosystem as thermal energy.
Bacteria eat the dead bodies of organisms to release the organisms’ stored energy into the atmosphere.
Some energy is transferred to the smaller organisms, and the rest is stored in the bodies of larger animals.
Some energy is transferred to the organisms, and the rest is released by plants in the form of carbon dioxide.
Bacteria eat the dead bodies of organisms, obtain all the energy, and store it in their bodies.
Answer:
some energy is transferred to the smaller organisms and the rest is stored in the bodies of larger animals
A scientist was studying a population of elephants. The first year, he counted a population of 80. Over the next eight years, the population's numbers were 94, 100, 103, 110, 125, 120, 125, 120. What appears to be the carrying capacity for this population? 120 124 125 126
Answer:
125
Explanation:
The correct option would be 125.
The carrying capacity of a particular environment generally refers to the maximum number of individuals of a particular species that the environment can support at a particular time based on the resources it has. Hence, the maximum population of a species will normally oscillate around the carrying capacity of the environment where it is found.
In the case of the elephants in the illustration, the maximum population recorded was 125. The population decreased from this value at some point only to increased back to it later.
Hence, the carrying capacity for the elephant is 125.
Answer:
125

why do wild plants need to reproduce sexually as well as asexually ?
Please answer correctly
Answer:
Wild plants would need to reproduce sexually so that there can be variation throughout the species to reduce the number of plants being at risks to certain diseases if the environment is changing. However, the wild plants need to produce asexually if the environment is stable.
Wild plants need to reproduce sexually as well as asexually in order to create variation within a species and lower the number of plants that are susceptible to specific illnesses in a changing environment.
What are wild plants?Wild plants would need to reproduce sexually. However, if the environment is stable, wild plants must reproduce asexually. Since male and female gametes are not mixed, asexual reproduction produces plants that are genetically similar to the parent plant and increases survival.
A seedling formed from a seed matures more slowly and is less robust than a cutting or bud is taken from an older plant.
Therefore, in order to diversify within a species and reduce the number of plants susceptible to specific diseases in a changing environment, wild plants must reproduce both sexually and asexually.

Which is an example of why the process of photosynthesis is important to life on Earth?
Grass uses photosynthesis to produce glucose, which is used within the grass for growth.
Fungi use photosynthesis to decompose dead and decaying plant matter.
Ectothermic animals use photosynthesis to convert sunlight into energy for cell functions.
Green plants use photosynthesis to remove oxygen gas from the atmosphere and replenish the earth’s carbon dioxide.
Which does not provide for enhanced genetic mixing?
A.Mix-matching
B.Random segregation
C.Crossing over
D.Fertilization that occurs through sexual reproduction
Answer:
A. Mix-matching
Explanation:
Sexual reproduction increases genetic variation in offspring by three main mechanisms: 1-random assortment of chromosomes during meiosis 2-genetic recombination, and 3-random fusion of gametes from different parents. In the first place, the pairs of homologous chromosomes are randomly oriented in metaphase I before they separate in Anaphase I. In consequence, daughter gamete cells receive different combinations of chromosomes. Second, recombination (also called crossing over) refers to the interchange of genetic material between non-sister chromatids during prophase I, thereby also increasing genetic variation in daughter cells. Third, the fusion of two haploid cells (i.e., gametes) in diploid organisms results in the formation of a single zygote cell that develops into a new organism, thereby the process of random fertilization between any two gametes generates different diploid zygotes, increasing thus genetic diversity.
What is the difference between food chains and food webs?
1. Food webs show the flow of energy from producers to consumers, and food chains show the flow of energy from consumers to producers.
2.Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
3.About ten percent of the energy is passed on to the next trophic level in food webs, but in food chains, about ninety percent is passed on to the next trophic level.
4.Heat is lost when energy is passed on to the next trophic level in food chains, but in food webs, heat is not lost when energy is passed on to the next trophic level.
Answer:
2. Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
Explanation:
A food chain is a single chain representing who eats whom in a system of organisms. A food web is a system of food chains, involving overlapping pathways of different foodchains.
Answer:
2.Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.
Explanation:
A food chain shows only a targeted path, while a food web shows a more realistic path. See attached photos.
First picture: Food Chain: Notice how it only shows one path from producer to tertiary consumer.
Second picture: Food Web: Notice the many pathing that connects for certain organisms in the food web. It shows a more realistic distribution of energy in a real world scenario.
A cloned mammal is made by removing the DNA from the unfertilized egg of an egg donor, replacing it with DNA from a cell of a mature animal, and then implanting that cell into the uterus of a surrogate mother. The cell then divides and behaves as if it were a regular embryo. Answer the following question(s) regarding a clone.Of whom is the baby a clone?
Answer:
The mature animal
Explanation:
The baby would be a clone of the mature animal whose DNA was placed in the unfertilized egg before being implanted into the uterus of a surrogate mother.
The DNA of the egg donor has been removed and replaced with the DNA of the mature animal. The surrogate mother is just a mere carrier and has no biological relationship with the clone. The only organism with biological relationship with the clone would be the one that donates its DNA, which in this case is the mature animal.
