Answer:
There are several reasons there is a bias in the fossil record, including the following: Hardbody parts fossilize better than soft-bodied parts. Fragile organisms are less likely to be preserved and fossilized. Fossils in remote areas are less like to be found compared to fossils in easily accessible regions.

The growth potential of alternative agricultural practices such as the growing of amaranth grain and the raising of deer, elk, emus, and buffalo for meat is limited because Group of answer choices it is impossible to domesticate new plants and animals the dietary laws in the United States are restrictive the animals and grain are difficult to raise the growers have not established an integrated commodity chain the high protein content of these meats and grains is thought to be unhealthy
Answer:
The growers have not established an integrated commodity chain
Explanation:
Integration of commodity chain includes merging of different alternative practices of agriculture for the overall growth of the society. It may raising cattle like sheep, lambs, cow or horses, etc. or raising deer, buffalo, emus and elk and also doing various plantation of crops such as wheat, barley, rice, coffee, cotton, etc.
But the farmers have not been able to established the integrated commodity chain because of which the growth potential of the alternative agricultural practices like raising emus or buffalos or growing amaranth grains is limited.
Gregor Mendel studied the inheritance pattern of several characteristics in pea plants. He observed that tall (T) plants were dominant to short (t) plants. If a heterozygous tall plant is crossed with a short plant, what percentage of the offspring will be short?
Answer:
Below
Explanation:
I used a punnett square to figure this out!
If you were to cross a heterozygous tall plant (Tt) with a short plant (tt), the possible resulting genotypes of the offspring would be:
50% chance of the offspring being heterozygous dominant (Tt)
50% chance of the offspring being short (tt)

Which statement describes the best evidence that two species share a recent common ancestor? NO LINKS NO NINKS
A) The species are about the same size.
B) The species eat the same type of food.
C) The species live in the same ecosystem.
D) The species have similar DNA sequences.
D.
Traits of two different organisms can be similar due to convergent evolution, that is, natural selection which favors the evolution of similar traits in species. The result of convergent evolution are analogous traits. These are traits which are similar but do not originate from a common ancestral trait. These can often be mistaken as homologous traits, which are traits that do originate from a common ancestor.
The take away here is that similarity of traits does not necessarily mean that two organisms shared a common ancestor.
However, by looking at the DNA sequences of the organisms we can determine if they truly shared a recent common ancestor or not.
Si un carnívoro requiere diariamente 3 000 calorías, ¿qué cantidad de energía procedente de un herbívoro necesitará? A su vez, el herbívoro, ¿qué cantidad de energía procedente del productor precisará? * Al hacer los cálculos recuerde la regla del 10%.
Answer:
Herbívoro: 30000 y productor: 300000.
Explicación:
Si un carnívoro requiere 3000 calorías por día, el carnívoro se comerá al herbívoro que tiene 30000 cantidad de energía y el herbívoro come 300000 cantidad de energía de las plantas porque de productor a herbívoro y de herbívoro a carnívoro, solo el 10 por ciento de la energía se transfiere mientras que el El 90 por ciento restante se libera en la atmósfera en forma de energía térmica, por lo que al usar la regla del 10 por ciento, el herbívoro come plantas en grandes cantidades y el carnívoro come herbívoros.

Q.3. Describe the structure of the internal and middle ear.
Answer:
The inner ear has two openings into the middle ear, both covered by membranes
Explanation:
The oval window lies between the middle ear and the vestibule, whilst the round window separates the middle ear from the scala tympani (part of the cochlear duct)
❈ The internal ear —
➥ The inner ear (also called the labyrinth) contains 2 main structures — the cochlea, which is involved in hearing, and the vestibular system (consisting of the 3 semicircular canals, saccule and utricle), which is responsible for maintaining balance.
➥ The cochlea is filled with fluid and contains the organ of Corti — a structure that contains thousands of specialised sensory hair cells with projections called cilia. The vibrations transmitted from the middle ear cause tiny waves to form in the inner ear fluid, which make the cilia vibrate.
➥ The hair cells then convert these vibrations into nerve impulses, or signals, which are sent via the auditory nerve to the brain, where they are interpreted as sound. The round window (fenestra cochlea) is a membrane that connects the cochlea with the middle ear. It helps dampen the vibrations in the cochlea.
➥ The semicircular canals also contain fluid and hair cells, but these hair cells are responsible for detecting movement rather than sound. When you move your head, the fluid within the semicircular canals (which sit at right angles to each other) also moves. This fluid motion is detected by the hair cells, which then send nerve impulses about the position of your head and body to the brain to allow you to maintain your balance.
➥ The utricle and saccule work in a similar way to the semicircular canals, allowing you to sense your body’s position relative to gravity and make postural adjustments as required.
❈ The middle ear —
➥ The middle ear is an air-filled space that contains 3 tiny bones (known as ossicles), called the malleus (hammer), incus and stapes (stirrup). Sound waves that reach the tympanic membrane cause it to vibrate.
➥ This vibration is then transmitted to the ossicles, which amplify the sound and pass on the vibration to the oval window (a thin membrane between the middle and inner ear). The Eustachian tube is a narrow tube that connects your middle ear to the back of your nose and throat (known as the nasopharynx). Its function is to allow air into the middle ear as well as drain mucus from the middle ear into the nasopharynx.
➥ When you swallow, your Eustachian tube opens up to allow air into the middle ear, so that the air pressure on either side of the tympanic membrane is the same. In situations when there is a sudden change in air pressure (e.g. during take-off and landing when travelling on a plane), the pressure in the middle ear is not the same as the outside air pressure.
➥ This can make your eardrum bulge or retract and less able to transmit vibrations, causing temporary hearing problems. By swallowing or ‘popping’ your ears, you can equalise the pressure.

b) abiotic
c) dead
d) living
2) What is biotic potential?
a) the number of individuals in a population at any time
b) the number of offspring produced in a population under limiting conditions of resources
c) the number of offspring produced in a population if there were no limits to resources
d) the number of offspring eaten by predators
Answer:
well number one would be abiotic and number 2 would be B
Explanation:
biotic is the ability of living things/species to increase under certain kind of condition or increase under evironmental conditions.
Explain how genetic mutations may result in genetic and physical variations (differences) within a population
The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism's DNA that create diversity within a population by introducing new alleles.

20. What type of relationship exists between the two animals in the cartoon
below?
Answer:
Predation
Explanation:
The bird is attacking the frog.
The type of relationship that exists between the two creatures is predation. So, the correct option is D.
What is Predation?Predation is a biological relationship that occurs when one creature, the predator, kills and consumes another organism, the prey. Predation is a widespread ecological occurrence that happens in a wide range of habitats and ecosystems, so it is an important strategy for managing prey species numbers.
Sharp teeth, claws, or beaks, powerful jaws, stealth movements, and camouflage are among the adaptations that predators use to capture and kill their prey. To discourage or mislead predators, prey species have evolved a variety of protective adaptations such as armor, spines, and contaminants, as well as behaviours like as hiding, running, or forming groups.
Therefore, the correct option is D.
