Frog temperature. Frogs are ectotherms, this means they gettheir heat from external sources. They are sometimes called 'cold blooded', but in fact they do not have cold blood, it is justregulated by their environment. In comparison, humans are endotherms and can maintain their body temperature at about 37°C.
Answer:
Larger habitats support populations with higher carrying capacities. Higher quality habitats support populations with higher carrying capacities. There is no difference in population growth rate between large and small habitats. Some major threats to biodiversity are: Habitat destruction/Deforestation, Introduced and invasive species, Genetic pollution, Over exploitation, Hybridization, Climate change, Diseases, Human overpopulation. If abiotic or biotic factors change, the carrying capacity changes as well. Natural disasters can destroy resources in an ecosystem. If resources are destroyed, the ecosystem will not be able to support a large population. This causes the carrying capacity to decrease.
Carrying capacity could be reduced if each individual within the species consumed less from the environment. Think about humans: if every human needs a four car garage and a large house, the planet can sustain fewer humans than if each human lived in a studio apartment and traveled using a bicycle. It would take 1.75 Earths to sustain our current population. If current trends continue, we will reach 3 Earths by the year 2050. It is beyond dispute that the modern industrial world has been able to temporarily expand Earth's carrying capacity for our species. As Nordhaus points out, population has grown dramatically (from less than a billion in 1800 to 7.6 billion today), and so has per capita consumption. Historically, habitat and land use change have had the biggest impact on biodiversity in all ecosystems, but climate change and pollution are projected to increasingly affect all aspects of biodiversity. Sustainable agriculture practices support integrating biodiversity in various ways including in terms of diversity of crops, traditional agriculture techniques to control pests and increase productivity as well as ensuring that farmed land is made up of a diverse mix of grazing land, crop land, orchards, wetlands and more.

Answer:
Due to genetic defects, a family history of hormone imbalances, or certain diseases.
Explanation:
According to the data, the blood is deficient in hormones which is due to a number of factors such as genetic defects, a family history of hormone imbalances, or certain diseases etc. The normal person has 10-20 units of hormones per ml of blood in their body, if the body has low in hormones the body does not perform its function properly that leads to certain diseases such as obesity, osteoporosis, and cardiovascular disease so we can say that genetic defects, hormone imbalances, or certain diseases are the causes of low in hormones.
Answer:
herbivore
Explanation:
An herbivore is an animal or insect that only eats vegetation, such as grasses, fruits, leaves, vegetables, roots and bulbs. Herbivores only eat things that need photosynthesis to live. This excludes insects, spiders, fish and other animals.
Answer:
Genes coding for proteins involved in chiasma formation.
Explanation:
Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.
Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.
