Answer:
Detritivores (also known as detrivores, detritophages, detritus feeders, or detritus eaters) are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as faeces). There are many kinds of invertebrates, vertebrates and plants that carry out coprophagy. By doing so, all these detritivores contribute to decomposition and the nutrient cycles. They should be distinguished from other decomposers, such as many species of bacteria, fungi and protists, which are unable to ingest discrete lumps of matter, but instead live by absorbing and metabolizing on a molecular scale (saprotrophic nutrition). However, the terms detritivore and decomposer are often used interchangeably but they are different organisms. Detritivore are usually arthropods and help in the process of remineralization. Detritivores perform the first stage of remineralization, by fragmenting the dead plant matter. Allowing for decomposers to perform the second stage of remineralization.
Decomposers are organisms that break down dead or decaying organisms; they carry out decomposition, a process possible by only certain kingdoms, such as fungi. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development. While the terms decomposer and detritivore are often interchangeably used, detritivores ingest and digest dead matter internally, while decomposers directly absorb nutrients through external chemical and biological processes. Thus, invertebrates such as earthworms, woodlice, and sea cucumbers are technically detritivores, not decomposers, since they must ingest nutrients - they are unable to absorb them externally.

To obtain energy from starch and glycogen, the body must begin by Group of answer choices converting both starch and glycogen to fatty acids. removing one glucose at a time with a condensation reaction. hydrolyzing both starch and glycogen to glucose. hydrolyzing the starch to glucose and the glycogen to amino acids.
Answer:
Hydrolyzing both starch and glycogen to glucose
Explanation:
Starch and glycogen are both forms of carbohydrates called "polysaccharide" found in the foods we consume. Polysaccharide are polymers that constitutes several monomeric units called monosaccharides. Monosaccharides are the forms in which the body can absorb energy.
Hence, starch and glycogen as polysaccharides must first be hydrolysed (broken down) into a monosaccharide called GLUCOSE in order to obtain energy for the body.
A scientist studies how the number of coyotes in San Diego County has changed over the last decade. Is this a population-level study, a community-level study, or an ecosystem-level study?
Answer:
Population level
Explanation:
Ecological studies can be performed at different hierarchy levels:
Organism Population CommunityEcosystemPopulations are groups of individuals from the same species, with similar characteristics, capable of crossing, leaving offspring, and living in the same habitat at the same time. These groups are reproductively isolated from other species groups. Individuals belonging to a species cannot reproduce with members of other species.What results of interest about this organization level is knowing the minimum size of the population needed to leave fertile offspring that ensure the population will survive over time. Genetic variability is also a significant factor because it allows evolutive adaptation to environmental changes. A population might be severely affected by evolutive forces such as genetic flow, genetic drift, and natural selection.
When analyzing the evolution of a population in time, there are parameters to consider regarding its size, such as the generational time, growth rate per capita, the net reproductive rate, the reproductive value, among others.
A community might be defined as a group of organisms of different species that coexist in a specific time and space.When ecologists talk about a Community, they refer to the existing interaction between different species that share the same habitat and at the same time. What results of interest about the study of this organization level are the inter-specific interactions. These interactions involve competition, predation, parasitism, mutualism, etcetera, and each species carries out a different role in these interactions. These relationships and the results are what determine the destiny of the populations and their size.
The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.• Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements.
• Biotic factors are all the living components in the ecosystem.
Biotic and abiotic factors influence the survival and reproduction of living beings. These are constantly interacting. If one of these components is removed, the whole ecosystem will change because its equilibrium has been altered.
Every abiotic component influence organisms and their survival and reproductive rates.
When analyzing how the number of coyotes in San Diego County has changed over the last decade, we are performing a population-level study. We need to know how the population changed its size through the years, but not the interactions with other species or abiotic factors. Interactions are not of interest in this study.

Research has shown that woolly mammoth populations decreased in a given area as the ecology of the area developed into extensive forests of birch and conifers. This type of vegetation was not favorable for the mammoth and was difficult to digest.
Which position regarding mammoth extinction does this evidence support?
A.
The mammoth became extinct because of overhunting.
B.
The mammoth became extinct because of habitat destruction by humans.
C.
The mammoth became extinct because the climate changed and its habitat was lost.
D.
The mammoth became extinct because mammoth physiology changed with the climate.
Answer:
D. The mammoth became extinct because mammoth physiology changed with the climate.
Explanation:
"ecology of the area developed into extensive forests of birch and conifers" and "not favorable for the mammoth and was difficult to digest." Infers that the mammoth became extinct due to its digestive system rejecting the food that the area provided. It's digestive system required different foods, thus starving them into extinction.
The position regarding mammoth extinction does this evidence support is The mammoth became extinct because mammoth physiology changed with the climate.
What is mammoth ?A mammoth is any species of the extinct elephantid genus Mammuthus, one of the many genera that make up the order of trunked mammals called proboscideans. The various species of mammoth were commonly equipped with long, curved tusks and, in northern species, a covering of long hair. They lived from the Pliocene epoch (from around 5 million years ago) into the Holocene at about 4,000 years ago, and various species existed in Africa, Europe, Asia, and North America. They were members of the family Elephantidae, which also contains the two genera of modern elephants and their ancestors. Mammoths are more closely related to living Asian elephants than African elephants.
The oldest representative of Mammuthus, the South African mammoth (M. subplanifrons), appeared around 5 million years ago during the early Pliocene in what is now southern and eastern Africa. Descendant species of these mammoths moved north and continued to propagate into numerous subsequent species, eventually covering most of Eurasia before migrating into North America around 1.5-1.3 million years ago, becoming ancestral to the Columbian mammoth (M. columbi). The last species to emerge, the woolly mammoth (M. primigenius), developed about 400,000 years ago in East Asia, with some surviving on Russia's Wrangel Island in the Arctic Ocean, as well as possibly the Taymyr Peninsula on mainland Siberia, until as recently as roughly 3,700 to 4,000 years ago, still extant during the construction of the Great Pyramid of ancient Egypt.

d. Jennifer Doudna
Answer:
a. Eric H. Davidson
Explanation:
Eric H. Davidson was a developmental biologist whose work helped to understand gene regulation networks in an evolutionary context, being a pioneer in understanding embryogenesis at the genome level. He especially studied sea urchin development, a model animal for developmental biology and genomics. He focused on the animal's nucleic acid properties through the process of hybridization (which has enabled us to understand molecular interactions during development as a whole system), shedding light on the molecular basis of sea urchin development. Eric H. Davidson also compiled the first list of 'fully sequenced' sea urchin genes, involving especially transcription factors, and their interactions with cis-regulatory sequences.

Cancer creates abnormal cells by disrupting
Answer:
New cells take the place of old or damaged cells as they die. Cancer disrupts this process and leads to abnormal growth in cells. It's caused by changes or mutations in DNA. DNA exists in the individual genes of every cell.
Explanation:
Cancer creates abnormal cells by disrupting the cell cycle. The cell cycle is a series of events that cells go through as they grow and divide. It is tightly regulated by a number of genes, and any disruption to these genes can lead to the development of cancer.
There are two main types of disruptions that can lead to cancer:
Mutations in genes that control the cell cycle. Mutations can cause cells to divide uncontrollably, or they can prevent cells from dying when they are supposed to.
Abnormalities in the way that genes are expressed. This can happen when genes are turned on or off at the wrong times, or when they are not expressed at all.
When the cell cycle is disrupted, cells can start to divide uncontrollably. This can lead to the formation of tumors, which are masses of abnormal cells.
Tumors can be benign, meaning that they are not cancerous, or they can be malignant, meaning that they are cancerous. Malignant tumors can spread to other parts of the body, which is a process called metastasis.
