write down one way that an animal loses some of energy it gets from a plant . please can someone help you get 20 points .
Answers
Answer:
There are several ways in which animals losses energy such as movement from place to place, muscle movement and respiration etc.
Explanation:
When animals such as deer, cow, rabbit etc feed on plants. Only 10 percent of energy is transferred from plants to the animal and the remaining is lost as heat energy in the atmosphere. This 10 percent of energy is used by the animals in muscle building and performing other activities such as movement and respiration. In respiration process, food molecules are broken down to produce energy and this energy is used in different processes.
Final answer:
The energy that animals obtain from plants is mostly lost as heat due to metabolic processes, with only about 10% retained in the animal's body tissue.
Explanation:
One way that an animal loses some of the energy it gets from a plant is through heat release during its metabolic processes. When an herbivore eats a plant, it uses the energy to maintain its bodily functions, such as movement, growth, and reproduction. During these activities, most of the energy is used and converted into heat, which is then lost to the environment. This is a demonstration of the second law of thermodynamics, which states that energy transfer leads to a loss of energy through heat. Only about 10% of the energy is retained and transformed into body tissue, while the rest is expended.
Why is symbiosis important to ecosystem functioning? Explain.
Answers
Answer:
Symbiotic relationships are important because they are a major driving force of evolution.
Explanation:
This networking and cooperation among species allows them to survive better than they would as individuals.
Your welcome :)
Final answer:
Symbiosis is crucial to ecosystem functioning as it often results in enhanced survival, establishment of nutrient cycles, and productivity of biomass between species. It influences resource competition, biodiversity, ecosystem structure, and resilience. Understanding these relationships is vital for ecosystem management and conservation efforts.
Explanation:
Symbiosis is critically important to ecosystem functioning because it often enhances the survival and productivity of biomass among different species. In a symbiotic relationship, organisms closely interact and usually at least one benefits, but there can be mutual benefits, neutral effects or even harm to the other. For example, nitrogen-fixing bacteria establish symbiotic relationships with leguminous plants, providing them with essential nitrogen in exchange for nutrients and a home. This interaction contributes to the nutrient cycle essential for ecosystem productivity.
Furthermore, symbiotic relationships such as those between microbes and plants or epiphytes and their host plants are central to maintaining ecological balance. These relationships allow for efficient nutrient exchange and can increase plants' resistance to environmental stressors, playing a pivotal role in the functioning of the ecosystem.
The significance of symbiosis extends beyond individual species, as it influences competition for resources, biodiversity, and the structure and resilience of ecosystems. Therefore, understanding symbiotic relationships is essential for conservation efforts and the sustainable management of ecosystems.

A tetraploid cell that divides by meiosis produces; Apply the concept you know about meiosis to answer this question.
Answers
Answer:
Diploid gametes
Explanation:
A tetraploid cell is a cell that has four sets of chromosomes i.e. 4n. Meiosis is a kind of cell division that reduces the chromosomal number of the daughter cells (gametes) by half.
Hence, a tetraploid cell will undergo meiosis to produce daughter cells (gametes) that have a diploid number of chromosomes each (2n). Since Meiosis is a reduction division, it occurs in a two-step division process viz: Meiosis I and II. Meiosis I involves separation of homologous chromosomes while meiosis II involves separation of replicated chromosomes.
In this case, a tetraploid (4n) will have two sets of chromosomes separated into opposite cells during meiosis I. This reduces the chromosome number into 2n (diploid).

Cross a heterozygous right-handed dad and a left-handed mom. What percent of left-handed kids would you expect?
Answers
Final answer:
When crossing a heterozygous right-handed dad with a left-handed mom, 50% of the offspring are expected to be left-handed. This conclusion is drawn from setting up a Punnett square that presents a ratio where half of the possible genotypes show the recessive trait (left-handedness).
Explanation:
To determine the percentage of left-handed kids from a cross between a heterozygous right-handed dad (Rr) and a left-handed mom (assuming left-handedness is recessive, rr), we can set up a Punnett square. The genotypes of their potential offspring would be as follows: Rr (right-handed) and rr (left-handed). Since left-handedness is recessive, both alleles (r) would be needed for a child to be left-handed.
According to standard Mendelian genetics, the Punnett square would look like this:
Rr (Right-handed heterozygote)rr (Left-handed)Rr (Right-handed heterozygote)rr (Left-handed)In this setup, 2 out of the 4 possible genotypes result in left-handedness. Therefore, we would expect 50% of the offspring to be left-handed. This is similar to predicting offspring genotypes in other genetic crosses. If we apply the same logic to the example of the cross between a white-eyed male and a female that is heterozygous for red eye color, we would have the following ratios:
25% of the offspring are males and hemizygous dominant with red eyes25% are male and hemizygous recessive with white eyes25% are female and heterozygous with red eyes25% are females and homozygous recessive with white eyesThis demonstrates a Mendelian 1:1 ratio when considering a specific trait within a sex (like eye color in males).

When is cladistics more useful than Linnaean taxonomy?

D. When you want to find organisms that look similar

Answers
Cladistics is more useful than Linnaean taxonomy when determining the order of evolution because it analyzes ancestor-descendant relationships and constructs phylogenetic trees, showing how species are related over time.
Explanation:The question asks, 'When is cladistics more useful than Linnaean taxonomy?'
If we consider what cladistics and Linnaean taxonomy are designed to do, cladistics is a method that is employed to decipher the ancestral-descendant relationships between species by comparing shared traits, and it is centered on the construction of phylogenetic trees or cladograms. In contrast, the Linnaean system classifies organisms based on observable physical traits, regardless of their evolutionary history. When we are concerned with understanding the evolutionary history or the order in which species have evolved, cladistics—and the clades it identifies—is demonstrably more informative. Therefore, the answer is A. When you want to determine the order of evolution.
Given the context, it becomes clear that phylogenetic classification through cladistics offers a framework to understand how species evolved over time, essentially providing a visual representation of these evolutionary relationships in the form of a tree, whereas Linnaean taxonomy might group organisms together based on similarities that might not reflect their evolutionary ancestry. For a robust understanding and classification that reflects evolutionary relationships, cladistics is often more useful than the Linnaean system.
The area drained by a river or river system is called a
Answers
The area drained by a river or river system is called a watershed or a drainage basin.
Explanation:The area drained by a river or river system is referred to as a drainage basin or watershed. This includes all the land surface drained by a series of streams that eventually flow into a single larger river. The point of origin of a river, usually in a highland area, is referred to as source water.
As the river flows away from the source, it becomes broader and slower due to the gradual decrease in gradient and increase in volume as tributaries add to it. This leads to an increase in the river's capacity to carry sediment, or silt, and simultaneously decreases the river's current, causing the silt to settle.
When the river reaches an ocean or a large lake, this area, where fresh and salt water mix, is often termed as an estuary. High silt content gets deposited in the form of deltas in marine areas with minimal waves and current.
