Areolar connective tissue contains collagen, reticular, and elastic fibers and is able to hold lots of fluid within the extracellular matrix.
What tissues include collagen reticular and elastic fibres?Loose connective tissue, which is made up of extracellular matrix and collagenous, elastic, and reticular fibres, serves to hold organs in place. Tendons and ligaments are made up of dense connective tissue, which is made up of a greater density of collagen fibres.
Where can you find collagen fibres in the body?Collagen is the most abundant protein in skin, tendons, ligaments, cartilage, bone, and connective tissue. Collagen tissues can be stiff (bone) or compliant (tendon) depending on the degree of mineralization, or they can have a gradient from rigid to compliant. Collagen accounts for around one-quarter of all protein in our bodies.

You may notice that the slope in the ice segment is steeper than the water segment.
Why is that?
a) Ice has a higher density than water and is therefore easier to melt
b) More heat is required to raise the temperature of ice
c) More heat is required to melt the ice than to evaporate it
d) More heat is required to raise the temperature of liquid water
The slope in the ice segment is steeper than in the water segment because more heat is required to raise the temperature of the ice.
Ice is heated by changing its phase from solid to liquid, or from ice to water. Melting is required to turn ice into water. Ice melts at 0 degrees Celsius. The temperature won't change until all the ice has melted. The temperature will begin to rise once all the ice has melted.
The transformation of water into gas comes next. Steam is produced when water boils. Water begins to vapourize at a temperature of 1000C. The temperature is unaffected by the phase change. Due to the strong intramolecular hydrogen bonds between water molecules, a large quantity of heat is needed. Before the water molecules can be transformed into vapors, the heat supplied is utilized to first break the hydrogen bonds between the water molecules. As a result, the ice segment's slope is steeper than the water segment's.

Marfan’s syndrome is a disease associated with faulty manufacture of the extracellular protein fibrillin. Since this is a component of elastin, in which of the numbered cells would the damaged gene be expressed?.
Marfan syndrome is related to an autosomal dominant condition.
There are several organs constructed of elastic fibres. Skin, skeletons, and joints are the most frequent organs. Marfan syndrome will show as the chest form, long as well as thin bones (arms, legs, fingers), stretch marks inside the skin, or eye lens.
Marfan syndrome, the genetic illness, affects connective tissue, or even the fibres that hold and attach the organs and other body parts. Marfan syndrome most usually affects the skeleton, blood vessels, heart, and vision. It occurs since the normal growth of connective tissue cannot continue with just one functional copy of such FBN1 gene.

Answer: GoodMorning: ) Ok so this happens When two oceanic plates are pushed away from each other, magma rises to the surface between the plates and creates a ridge.
Explanation: In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading (Fig. 7.21). Hot magma rises to the crust's surface, cracks develop in the ocean floor, and the magma pushes up and out to form mid-ocean ridges.

How does the function of keratinized stratified squamous epithelium differ from the function of unkeratinized stratified squamous epithelium? give examples of locations for each.
Keratinized stratified squamous epithelium differs from the function of nonkeratinized stratified squamous epithelium in that non-keratinized epithelium is permeable to water whereas cornified epithelium is impermeable to water. Moreover, the keratinized epithelium is an effective barrier, whereas the non-keratinized epithelium is a less effective barrier.
What is keratinized epithelium?
Keratinized epithelium is a stratified squamous epithelium found in the skin, the epidermis of the palms and soles, and masticatory mucosa. The keratinized epithelium forms an effective barrier. Its surface layer consists of dead cells. Keratin deposits on the surface. The cytoplasm of surface cells is replaced by keratin proteins. The keratinized epithelium is therefore dry and impermeable to water. It also provides better protection against scratches.
What is non-keratinized epithelium?
The non-cornified epithelium is a stratified squamous epithelium found in the lips, oral mucosa, alveolar mucosa, soft palate, the underside of the tongue, and the floor of the mouth. Unlike keratinized epithelium, the non-keratinized epithelium is moist and contains living cells in the superficial layer.

Even a country in which the birthrate and death rate are equal can experience population growth if it also has.
Even a country in which the birthrate and death rate are equal can experience population growth if it also has immigration.
In evolutionary time, migration will often quickly converge gene frequencies among populations. Migration is a powerful mechanism for balancing the gene frequencies of subpopulations in a species in the absence of selection. Gene frequencies will eventually equalize if the migration rate is larger than zero.Migration refers to the movement of people, groups, or populations. Migration facilitates gene flow, or the transfer of genes from one population to another, in terms of genetics. Migration—or, to be more precise, gene flow—alone will quickly bring the gene frequencies of the two populations together if they initially had distinct gene frequencies and if selection is not at work.Therefore, immigration is the correct answer.

A selection pressure for the development of flower petals might have been: group of answer choices increased attraction for pollinators all are correct increased attraction for predators increased surface area for wind pollination
All are correct, the development of flower petals might cause increased attraction for pollinators, increased attraction for predators, and increased surface area for wind pollination.
Flowers' reproductive organs are encircled by petals, which are modified leaves. To draw pollinators, they are frequently brightly colored or shaped differently. The corolla is the collective name for a flower's petals. Functions of the petal include scent production and color changing which is used to attract pollinators and also attract predators.
Flowers also exhibit different types of pollination and wind pollination is one of it, for flowers that undergo wind pollination require little or no petal since the pollens are to be scattered by wind.

Where would the lac repressor be bound in a e. coli cell that is growing in low glucose and high lactoze?
Repressor changes its conformation when it binds to lactose, which prevents it from binding to DNA. This enables the transcription of the lactose operon.
What transpires to the lac operon when lactose is absent?The lac operon is turned off in the absence of lactose. This occurs because a protein called a repressor attaches to the operator region. This prevents RNA polymerase from attaching to the operon, which in turn stops the structural genes from being transcribed. Allolactose, which binds to the repressor protein, is created when lactose is present. As a result, the repressor protein loses its ability to bind to the operator region and inhibit transcription. This enables the three structural genes for beta-galactosidase, beta-galactosidase permease, and beta-galactosidase transacetylase to bind and be translated by RNA polymerase.Learn more about the lac operon with the help of the given link:

b. a bacterial membrane protein
c. lps (lipopolysaccharide)
d. a molecule of cyclic amp (camp)
Option D: All of the following would likely be an antigen except a molecule of the cyclic amp (cAMP).
Cyclic adenosine monophosphate is a derivative of adenosine triphosphate (ATP). It is important for many biological processes involving intracellular transduction in various organisms. cAMP is synthesized by adenylate cyclase, an enzyme located on the inner side of the plasma membrane. Various G proteins are responsible for the activation and inhibition of adenylate cyclase.
cAMP regulates glycogen, sugar, and lipid metabolism. It acts as an intracellular messenger to transfer the effects of hormones like glucagon and adrenaline into the cells. It activates protein kinases and also regulates the function of ion channels by binding with them.
Since, viral spike proteins, bacterial membrane proteins, and lipopolysaccharides all act as antigens by triggering the immune system where cAMP is involved in the transmission of various signals. Therefore, it can be said that cAMP is not an antigen.
